 ## Installation & Setup
 
+### Platform Support Matrix
+
+| Platform | Status | Package Manager | Notes |
+|----------|--------|----------------|-------|
+| macOS (Intel) | ✅ Fully Supported | Homebrew | Main development platform |
+| macOS (ARM) | ✅ Fully Supported | Homebrew | Rosetta for compatibility |
+| Ubuntu/Debian | ✅ Fully Supported | apt-get | Tested on 20.04+ |
+| Fedora/RHEL | ✅ Fully Supported | dnf | Tested on Fedora 38+ |
+| Arch Linux | ✅ Fully Supported | pacman | AUR via yay (optional) |
+| WSL1/WSL2 | ✅ Fully Supported | apt-get/dnf/pacman | Based on distro |
+
 ### Initial Installation
+
 ```bash
-# Fresh install (from remote)
+# Fresh install (from remote) - Auto-detects OS
 bash <(curl -L https://raw.githubusercontent.com/jrock2004/dotfiles/main/scripts/curl-install.sh)
 
-# Local install
+# Local install - Interactive mode
 ./install.sh
+
+# Non-interactive install (CI/automation)
+./install.sh --non-interactive
+
+# Dry-run (preview without executing)
+./install.sh --dry-run
+
+# Install only specific components
+./install.sh --only shell,neovim,tmux
+
+# Skip specific components
+./install.sh --skip lua,rust
 ```
 
-The installer will:
-1. Ask for OS choice (Mac OSX only currently supported)
-2. Install Homebrew if not present
-3. Run `brew bundle` to install all dependencies from Brewfile
-4. Set up directories, FZF, Lua, Neovim, Rust, Volta, tmux, and Claude CLI
-5. Use Stow to symlink all files from `files/` to `$HOME`
+### Installation Process
+
+The modular installer will:
+1. **Detect OS and architecture** (macOS/Linux/WSL, Intel/ARM)
+2. **Install package manager** if not present (Homebrew/apt/dnf/pacman)
+3. **Install packages** from cross-platform package files
+4. **Set up components** based on selection (shell, neovim, tmux, rust, volta, etc.)
+5. **Configure OS-specific features** (macOS defaults, WSL systemd, etc.)
+6. **Symlink dotfiles** using GNU Stow from `files/` to `$HOME`
+7. **Create backups** before overwriting existing configs
+
+### CLI Flags
+
+```bash
+# Display help
+./install.sh --help
+
+# Show version
+./install.sh --version
+
+# List all available components
+./install.sh --list-components
+
+# Preview actions without executing
+./install.sh --dry-run
+
+# Skip all prompts (use defaults)
+./install.sh --non-interactive
+
+# Force reinstall even if already installed
+./install.sh --force
+
+# Skip specific components
+./install.sh --skip <component1>,<component2>
+
+# Install only specific components
+./install.sh --only <component1>,<component2>
+```
+
+### Configuration File
+
+Create `~/.dotfiles.env` to set default options:
+
+```bash
+# Skip specific components
+SKIP_COMPONENTS="rust,lua"
+
+# Install only specific components
+ONLY_COMPONENTS="shell,neovim"
+
+# Custom backup location
+BACKUP_DIR="$HOME/.config/dotfiles-backups"
+
+# Force specific package manager
+PACKAGE_MANAGER="brew"  # or apt, dnf, pacman
+
+# Non-interactive mode
+NON_INTERACTIVE=true
+
+# Dry-run mode
+DRY_RUN=true
+
+# Force reinstall
+FORCE_INSTALL=true
+
+# Custom log file
+LOG_FILE="$HOME/.dotfiles-install.log"
+
+# Desktop environment flag
+USE_DESKTOP_ENV=true
+
+# Override OS detection
+OS="linux"  # or macos, wsl
+```
+
+See `.dotfiles.env.example` for all available options.

+
+### Package Management System
+
+The dotfiles use a **cross-platform package management system** that:
+- Defines common tools in `packages/common.txt` (should exist on all platforms)
+- Defines optional tools in `packages/optional.txt` (nice-to-have)
+- Uses OS-specific package files for platform-specific tools
+- Maps package names across platforms via `packages/mappings/*.map`
+- Validates package consistency with `scripts/validate-packages.sh`
+
+**Package abstraction layer** (`scripts/lib/package-manager.sh`):
+- `pkg_install()`: Installs packages using appropriate package manager
+- `pkg_update()`: Updates all packages
+- Supports: Homebrew, apt-get, dnf, pacman, flatpak, snap
+- Handles package name lookups via mapping files
+- Gracefully handles optional packages (warns but continues)
+
+**Example**: Installing `fd` (file search tool)
+- macOS: `brew install fd`
+- Ubuntu: `apt-get install fd-find` (mapped via `common-to-ubuntu.map`)
+- Arch: `pacman -S fd`
+- Fedora: `dnf install fd-find`
+
+### Component-Based Architecture
+
+The installation system is **modular and component-based**:
+
+**Available Components**:
+- `directories`: Create standard directories (~/.local/bin, ~/projects, etc.)
+- `homebrew`: Install Homebrew and packages (macOS)
+- `vscode`: Install VS Code extensions
+- `fonts`: Install Nerd Fonts
+- `claude`: Install Claude Code CLI
+- `fzf`: Install FZF (fuzzy finder)
+- `lua`: Install Lua language server
+- `neovim`: Install Neovim dependencies (pynvim)
+- `rust`: Install Rust toolchain (rustup)
+- `shell`: Configure zsh, zap plugin manager
+- `tmux`: Install Tmux Plugin Manager (tpm)
+- `volta`: Install Volta and Node.js
+- `stow`: Symlink dotfiles with GNU Stow
+- `macos-defaults`: Configure macOS defaults (macOS only)
+
+**Component Dependencies**:
 ```
+directories → none
+shell → git, curl, zsh, brew (optional)
+neovim → python, pip
+tmux → git, curl
+rust → curl, bash
+volta → curl, bash
+lua → git, curl, luarocks (optional)
+claude → curl, bash
+stow → stow
+```
+
+Components are **idempotent** (safe to run multiple times) and include:
+- Pre-installation checks (skip if already installed)
+- Retry logic for network operations
+- Rollback on failure
+- Progress tracking
+- Detailed logging
+
+### OS Detection and Platform-Specific Setup
+
+**Detection** (`scripts/lib/detect.sh`):
+- Detects OS: macOS, Linux, WSL
+- Detects distro: Ubuntu, Debian, Fedora, Arch, etc.
+- Detects architecture: x86_64, arm64, aarch64
+- Exports: `$OS`, `$DISTRO`, `$ARCH`, `$BREW_PREFIX`, `$IS_WSL`
+
+**Platform Orchestration** (`scripts/os/*.sh`):
+- **macOS** (`os/macos.sh`): Xcode CLI tools, Homebrew, Rosetta (ARM)
+- **Linux** (`os/linux.sh`): Build tools, package manager setup, Starship
+- **WSL** (`os/wsl.sh`): systemd, Windows interop, clipboard integration
+
+**Conditional Configuration**:
+- `.zshrc` detects OS and loads appropriate theme (Powerlevel10k vs Starship)
+- Stow skips platform-specific configs (e.g., yabai on Linux, i3 on macOS)
+- Package installation uses OS-appropriate package manager
+- Fonts installed differently (Homebrew on macOS, ~/.local/share/fonts on Linux)

+
+### UI/UX Library
+
+The installer includes a UI library (`scripts/lib/ui.sh` and `scripts/lib/gum-wrapper.sh`) that:
+- Uses **gum** if available (optional dependency)
+- Falls back to **fzf** or **bash select** if gum not installed
+- Provides colored output, symbols (✓, ✗, →, ℹ, ⚠)
+- Implements progress bars and spinners
+- Handles interactive prompts with graceful fallbacks
+
+**Wrapper functions**:
+- `ui_choose()`: Single selection (gum choose → fzf → select)
+- `ui_multi_select()`: Multi-selection (gum choose --no-limit → fzf --multi)
+- `ui_confirm()`: Yes/no prompts (gum confirm → read -p)
+- `ui_input()`: Text input (gum input → read -p)
+- `ui_spin()`: Spinner for background tasks
+
+All prompts are skipped when `--non-interactive` flag is set.
+
+### Error Handling and Reliability
+
+**Error Handling** (`scripts/lib/common.sh`):
+- `set -euo pipefail` in all scripts (exit on error, undefined vars, pipe failures)
+- `trap` for cleanup on error (ERR, EXIT, INT, TERM signals)
+- `error_handler()`: Logs errors with stack trace
+- `cleanup_on_error()`: Automatic rollback to backups
+
+**Backup System**:
+- Backups created before overwriting configs
+- Timestamp-based backup directories: `~/.dotfiles.backup.<timestamp>`
+- Automatic restore if installation fails
+- Manual restore with `restore_backup()` function
+
+**Retry Logic**:
+- Network operations (curl, git clone) retry up to 3 times
+- Exponential backoff between retries
+- `retry_command()` wrapper function in common.sh
+
+**Logging**:
+- `log_info()`, `log_success()`, `log_warning()`, `log_error()`
+- Timestamps on all log messages
+- Optional log file via `LOG_FILE` env variable
+- Progress tracking (e.g., "Step 3/10")
+
+### Testing Infrastructure
+
+**Testing Tools**:
+- **ShellCheck**: All 27 scripts pass shellcheck validation
+- **Integration tests**: `scripts/test-integration.sh` (verifies installation)
+- **Docker tests**: `test/test-docker.sh` (Ubuntu, Fedora, Arch containers)
+- **CI/CD**: GitHub Actions (`.github/workflows/test-install.yml`)
+
+**Running Tests**:
+```bash
+# ShellCheck linting

 ### Installing New Packages
 
+**Cross-platform tools** (should work on all OSes):
+```bash
+# Add to packages/common.txt
+echo "newtool" >> packages/common.txt
+
+# Add platform-specific name mappings if needed
+echo "newtool=newtool-bin" >> packages/mappings/common-to-ubuntu.map
+
+# Validate
+./scripts/validate-packages.sh
+
+# Install
+./scripts/install.sh --only homebrew
+```
+
+**macOS-only tools**:
 ```bash
-# Install via Homebrew (preferred for system tools)
-brew install <package>
-brew install --cask <app>
+# Add to appropriate file
+echo "package-name" >> packages/macos/core.txt           # CLI tool
+echo "app-name" >> packages/macos/gui-apps.txt           # GUI app (cask)
+echo "font-name" >> packages/macos/fonts.txt             # Font
+echo "yabai" >> packages/macos/macos-only.txt            # macOS-specific
 
-# Update Brewfile to persist
-brew bundle dump --force
+# For Homebrew taps
+echo "homebrew/cask-fonts" >> packages/macos/taps.txt
 
-# Install Node packages globally via Volta
+# Reinstall packages
+./scripts/install.sh --only homebrew --force
+```
+
+**Linux-only tools**:
+```bash
+# Add to appropriate file
+echo "package-name" >> packages/linux/core.txt           # Distribution package
+echo "flatpak-id" >> packages/linux/gui-apps-flatpak.txt # Flatpak
+echo "snap-name" >> packages/linux/gui-apps-snap.txt     # Snap
+
+# Reinstall
+./scripts/install.sh --only homebrew --force
+```
+
+**Node packages via Volta**:
+```bash
+# Install globally via Volta
 volta install <package>
 
 # Or use the alias (installs common language servers)
 npmpackages
 ```
 
+**Migrating from old Brewfile**:
+```bash
+# Run migration script
+./scripts/migrate-brewfile.sh
+
+# Validates mapping and reports differences
+```
+
+### Package Validation
+
+```bash
+# Validate package consistency
+./scripts/validate-packages.sh
+
+# This checks:
+# - All common packages have mappings for each platform
+# - No duplicate packages across files
+# - Package name format is correct
+# - Reports missing packages per OS
+```
+
+### Updating Dotfiles
+
+```bash
+# Pull latest changes and re-apply
+./update.sh
+
+# Update without updating packages
+./update.sh --no-packages
+
+# Update without restarting services
+./update.sh --no-restart
+
+# Preview update without executing
+./update.sh --dry-run
+```
+
+The update script will:
+1. Show git diff of changes
+2. Pull latest changes from git
+3. Optionally update installed packages
+4. Re-run stow for new configs
+5. Optionally restart services (tmux, yabai, etc.)
+6. Create backup before updating
+
+### Uninstalling

 ## Important Notes
 
-- **macOS only**: Currently only supports Mac OSX
+- **Cross-platform**: Supports macOS, Linux (Ubuntu, Fedora, Arch), and WSL
 - **Stow-based**: Never edit files in `$HOME` directly; edit in `files/` then run `sync`
-- **Homebrew**: Main package manager, uses rosetta for Volta/Node compatibility
+- **Package managers**: Homebrew (macOS), apt/dnf/pacman (Linux), automatic detection
 - **Volta**: Manages Node.js versions (not nvm/fnm)
 - **LazyVim**: Base Neovim config - consult LazyVim docs for built-in features
 - **Shell**: Uses zsh (not bash), switched automatically during install
 - **Git config**: `.gitconfig` is managed via Stow, so user-specific changes should be in `files/.gitconfig`
+- **Modular**: Component-based architecture, skip or install only what you need
+- **Idempotent**: Safe to run multiple times, includes rollback on failure
+- **Tested**: CI/CD pipeline, Docker tests, integration tests, ShellCheck validation
+
+## Migration from Old System
+
+If upgrading from the old monolithic install.sh:
+
+1. **Backup your current setup**:
+   ```bash
+   cp -r ~/.dotfiles ~/.dotfiles.backup.old
+   ```
+
+2. **Pull latest changes**:
+   ```bash
+   cd ~/.dotfiles
+   git pull origin main
+   ```
+
+3. **Review breaking changes** (see `MIGRATION.md` when created)
+
+4. **Run new installer**:
+   ```bash
+   ./install.sh --dry-run  # Preview first
+   ./install.sh            # Then install
+   ```
+
+5. **Migrate Brewfile** (macOS only):
+   ```bash
+   ./scripts/migrate-brewfile.sh
+   ```
+
+The old `Brewfile` is kept for backward compatibility but will be deprecated in a future release.

+
+## Adding New Packages
+
+### Cross-Platform Packages
+
+For tools that should be available on **all platforms** (macOS, Linux, WSL):
+
+1. **Add to `packages/common.txt`**:
+   ```bash
+   echo "your-package-name" >> packages/common.txt
+   ```
+
+2. **Create mappings** for platforms where package name differs (see [Creating Package Mappings](#creating-package-mappings))
+
+3. **Validate** the package configuration:
+   ```bash
+   ./scripts/validate-packages.sh
+   ```
+
+4. **Test installation** on multiple platforms if possible:
+   ```bash
+   # macOS
+   ./install.sh --only homebrew --force --dry-run
+
+   # Linux (Docker)
+   ./test/test-docker.sh ubuntu --build
+   ```
+
+**Example**: Adding `htop` (cross-platform monitoring tool)
+```bash
+# Add to common.txt
+echo "htop" >> packages/common.txt
+
+# Validate
+./scripts/validate-packages.sh
+
+# Test
+./install.sh --only homebrew --dry-run
+```
+
+### Platform-Specific Packages
+
+For packages that are **platform-specific**:
+
+#### macOS-Specific
+
+```bash
+# CLI tools
+echo "package-name" >> packages/macos/core.txt
+
+# GUI applications (Homebrew casks)
+echo "app-name" >> packages/macos/gui-apps.txt
+
+# Fonts
+echo "font-name" >> packages/macos/fonts.txt
+
+# macOS-only tools (yabai, skhd, etc.)
+echo "tool-name" >> packages/macos/macos-only.txt
+
+# Homebrew taps (if needed)
+echo "homebrew/tap-name" >> packages/macos/taps.txt
+```
+
+#### Linux-Specific
+
+```bash
+# Distribution packages
+echo "package-name" >> packages/linux/core.txt
+
+# GUI applications (native)
+echo "app-name" >> packages/linux/gui-apps.txt
+
+# Flatpak applications
+echo "com.example.App" >> packages/linux/gui-apps-flatpak.txt
+
+# Snap applications
+echo "app-name" >> packages/linux/gui-apps-snap.txt
+```
+
+#### WSL-Specific
+
+```bash
+# WSL-specific utilities
+echo "package-name" >> packages/wsl/wsl-specific.txt
+```
+
+### Optional Packages
+
+For **nice-to-have** tools that may not be available on all platforms:
+
+```bash
+echo "optional-tool" >> packages/optional.txt
+```
+
+The installer will warn but continue if these packages are unavailable.
+
+## Creating Package Mappings
+
+When a package has **different names** across platforms, create a mapping:
+
+### Mapping File Format
+
+```
+# Format: common-name=platform-specific-name
+fd=fd-find
+bat=batcat
+ripgrep=rg
+```
+
+### Adding Mappings
+
+1. **Identify the common name** (used in `packages/common.txt`)
+2. **Find platform-specific names**:
+   - Ubuntu/Debian: `apt-cache search <name>`
+   - Fedora: `dnf search <name>`
+   - Arch: `pacman -Ss <name>`
+   - macOS: `brew search <name>`
+
+3. **Add to appropriate mapping file**:
+   ```bash
+   # Ubuntu/Debian
+   echo "fd=fd-find" >> packages/mappings/common-to-ubuntu.map
+
+   # Fedora
+   echo "fd=fd-find" >> packages/mappings/common-to-fedora.map
+
+   # Arch (if different)
+   echo "fd=fd" >> packages/mappings/common-to-arch.map
+
+   # macOS (usually same as common name)
+   echo "fd=fd" >> packages/mappings/common-to-macos.map
+   ```
+
+4. **Validate mappings**:
+   ```bash
+   ./scripts/validate-packages.sh
+   ```
+
+### Example: Adding `eza` (modern `ls` replacement)
+
+```bash
+# 1. Add to common.txt
+echo "eza" >> packages/common.txt
+
+# 2. Create mappings (if needed)
+# Ubuntu - check if name differs
+apt-cache search eza
+# Fedora - check if name differs
+dnf search eza
+# Add mappings if different from "eza"
+
+# 3. Validate
+./scripts/validate-packages.sh
+```
+
+## Adding New Components
+
+Components are modular installation units (e.g., `shell`, `neovim`, `tmux`).
+
+### Creating a New Component
+
+1. **Create component file** in `scripts/components/<name>.sh`:
+   ```bash
+   touch scripts/components/<name>.sh
+   chmod +x scripts/components/<name>.sh
+   ```
+
+2. **Define component function**:
+   ```bash
+   #!/bin/bash
+   # Component: <name>
+   # Description: What this component does
+   # Dependencies: list, of, dependencies
+   # Platforms: macos, linux, wsl (or "all")
+
+   setup_<name>() {
+       local component="<name>"
+
+       # Idempotency check
+       if [ -f "$HOME/.<name>-installed" ] && [ "$FORCE_INSTALL" != "true" ]; then
+           log_info "$component already installed (use --force to reinstall)"
+           return 0
+       fi
+
+       log_info "Installing $component..."
+
+       # Installation steps here
+       # Example:
+       # pkg_install "package-name" || {
+       #     log_error "Failed to install package-name"
+       #     return 1
+       # }
+
+       # Mark as installed
+       touch "$HOME/.<name>-installed"
+
+       log_success "$component installed successfully"
+       return 0
+   }
+   ```
+
+3. **Add to component list** in `scripts/install.sh`:
+   ```bash
+   # In show_help() function
+   echo "  - <name>              Description of component"
+   ```
+
+4. **Add to OS orchestration** in `scripts/os/macos.sh`, `scripts/os/linux.sh`, or `scripts/os/wsl.sh`:
+   ```bash
+   # Source the component
+   source "$SCRIPT_DIR/components/<name>.sh"
+
+   # Add to installation sequence
+   run_component "<name>" "setup_<name>"
+   ```
+
+5. **Document dependencies** in component file header
+
+6. **Test the component**:
+   ```bash
+   ./install.sh --only <name> --dry-run
+   ./install.sh --only <name> --force
+   ```
+
+### Component Best Practices
+
+- **Make it idempotent**: Check if already installed, use `--force` to override
+- **Handle errors gracefully**: Use `|| return 1` for critical failures
+- **Log progress**: Use `log_info`, `log_success`, `log_warning`, `log_error`
+- **Support dry-run**: Check `$DRY_RUN` variable before executing
+- **Retry network operations**: Use `retry_command` for downloads
+- **Document dependencies**: List in file header
+
+### Example Component
+
+See `scripts/components/shell.sh` or `scripts/components/tmux.sh` for complete examples.
+
+## Testing
+
+### Running Tests Locally
+
+#### ShellCheck (Required)
+
+All shell scripts must pass ShellCheck:
+
+```bash
+# Check all scripts
+./scripts/test-shellcheck.sh
+
+# Check specific script
+shellcheck scripts/install.sh
+```
+
+**Fix common issues**:
+- Quote variables: `"$VAR"` not `$VAR`
+- Check exit codes: `command || handle_error`
+- Use `[[ ]]` for tests, not `[ ]`
+
+#### Integration Tests
+
+Test that installation works correctly:
+
+```bash
+# Run all integration tests
+./scripts/test-integration.sh
+
+# This tests:
+# - Dotfiles are symlinked correctly
+# - Required binaries are installed
+# - Shell is changed to zsh
+# - Neovim starts without errors
+# - Git, tmux, volta work correctly
+```
+
+#### Docker Tests
+
+Test on multiple Linux distributions:
+
+```bash
+# Test on Ubuntu
+./test/test-docker.sh ubuntu --build
+
+# Test on Fedora
+./test/test-docker.sh fedora --build
+
+# Test on Arch
+./test/test-docker.sh arch --build
+
+# Test on all distros
+for distro in ubuntu fedora arch; do
+    ./test/test-docker.sh "$distro" --build
+done
+
+# Drop into shell for debugging
+./test/test-docker.sh ubuntu --build --shell
+```
+
+#### Dry-Run Testing
+
+Always test with dry-run before actual installation:
+
+```bash
+# Preview installation
+./install.sh --dry-run
+
+# Preview specific component
+./install.sh --only <component> --dry-run
+
+# Preview with different settings
+DRY_RUN=true ./install.sh
+```
+
+### CI/CD Testing
+
+Pull requests are automatically tested via GitHub Actions:
+- **macOS**: Tests on macOS-latest
+- **Linux**: Tests on ubuntu-latest
+- **ShellCheck**: All scripts must pass
+- **Dry-run**: Validates installation process
+- **Package validation**: Checks package consistency
+
+View CI results at: `.github/workflows/test-install.yml`
+
+### Adding New Tests
+
+To add new integration tests, edit `scripts/test-integration.sh`:
+
+```bash
+test_your_feature() {
+    log_info "Testing your feature..."
+
+    # Your test logic here
+    if [ condition ]; then
+        log_success "Feature test passed"
+        return 0
+    else
+        log_error "Feature test failed"
+        return 1
+    fi
+}
+
+# Add to main test sequence
+test_your_feature || exit 1
+```
+
+## Code Style Guidelines
+
+### Shell Script Style
+
+Follow the [Google Shell Style Guide](https://google.github.io/styleguide/shellguide.html) with these key points:
+
+#### 1. Shebang and Settings
+
+```bash
+#!/bin/bash
+# Description of script
+# Exit on error, undefined variables, and pipe failures
+set -euo pipefail
+```
+
+#### 2. Error Handling
+
+```bash
+# Use error handling
+command || {
+    log_error "Command failed"
+    return 1
+}
+
+# Use trap for cleanup
+trap cleanup_on_error ERR EXIT INT TERM
+```
+
+#### 3. Functions
+
+```bash
+# Function naming: lowercase with underscores
+function_name() {
+    local var="value"  # Use local for function variables
+
+    # Do something
+    return 0
+}
+```
+
+#### 4. Variables
+
+```bash
+# Global variables: UPPERCASE
+GLOBAL_VAR="value"
+
+# Local variables: lowercase
+local_var="value"
+
+# Always quote variables
+echo "$var"
+echo "${var}"
+
+# Use arrays properly
+my_array=("item1" "item2")
+for item in "${my_array[@]}"; do
+    echo "$item"
+done
+```
+
+#### 5. Conditionals
+
+```bash
+# Use [[ ]] for tests
+if [[ "$var" == "value" ]]; then
+    # Do something
+fi
+
+# Check exit codes
+if command; then
+    # Success
+else
+    # Failure
+fi
+```
+
+#### 6. Logging
+
+```bash
+# Use logging functions
+log_info "Information message"
+log_success "Success message"
+log_warning "Warning message"
+log_error "Error message"
+```
+
+#### 7. Comments
+
+```bash
+# File header
+#!/bin/bash
+# Script: name.sh
+# Description: What this script does
+# Dependencies: what it needs
+# Platforms: macos, linux, wsl
+
+# Function documentation
+# Description: What the function does
+# Arguments: $1 - description
+# Returns: 0 on success, 1 on failure
+function_name() {
+    # Implementation
+}
+```
+
+### ShellCheck Rules
+
+All scripts must pass ShellCheck with our configuration (`.shellcheckrc`):
+
+**Disabled warnings** (with justification):
+- `SC2155`: Declare and assign separately (allows `local var="$(command)"`)
+- `SC2034`: Variable appears unused (for exported variables)
+- `SC2086`: Double quote to prevent globbing (sometimes needed)
+- `SC2059`: Don't use variables in printf format (allows dynamic formats)
+- `SC2129`: Multiple redirects (allows `echo >> file` style)
+- `SC1091`: Not following sourced files (can't follow dynamic sources)
+
+**Enabled and enforced**:
+- Quote all variables
+- Check command exit codes
+- Use `[[ ]]` for tests
+- Proper array handling
+- No unused variables (except exports)
+
+### Commit Message Format
+
+Use [Conventional Commits](https://www.conventionalcommits.org/):
+
+```
+<type>(<scope>): <description>
+
+[optional body]
+
+[optional footer]
+```
+
+**Types**:
+- `feat`: New feature
+- `fix`: Bug fix
+- `docs`: Documentation changes
+- `style`: Code style (formatting, no logic change)
+- `refactor`: Code refactoring
+- `test`: Adding or updating tests
+- `chore`: Maintenance tasks
+
+**Examples**:
+```bash
+feat(packages): Add support for Neovim 0.10
+fix(shell): Fix zsh plugin loading order
+docs(readme): Update installation instructions
+test(docker): Add Fedora 39 test
+chore(ci): Update GitHub Actions versions
+```

+## What's Changed
+
+### Version 2.0.0 (Current)
+
+The new version introduces a **modular, component-based architecture** with **cross-platform support**:
+
+#### Major Improvements
+
+1. **Cross-Platform Support**
+   - **Old**: macOS only
+   - **New**: macOS, Ubuntu, Fedora, Arch Linux, WSL
+
+2. **Package Management**
+   - **Old**: Single `Brewfile` (Homebrew only)
+   - **New**: Cross-platform package system with mappings
+     - `packages/common.txt` - Cross-platform tools
+     - `packages/optional.txt` - Optional tools
+     - `packages/macos/` - macOS-specific packages
+     - `packages/linux/` - Linux-specific packages
+     - `packages/wsl/` - WSL-specific packages
+     - `packages/mappings/` - Package name mappings
+
+3. **Installation System**
+   - **Old**: Monolithic `install.sh` (1159 lines)
+   - **New**: Modular architecture (339-line main script + components)
+     - `scripts/lib/` - Shared libraries
+     - `scripts/os/` - OS-specific orchestration
+     - `scripts/components/` - Component setup functions
+
+4. **New Features**
+   - Component-based installation (install only what you need)
+   - Dry-run mode (`--dry-run`)
+   - Non-interactive mode (`--non-interactive`)
+   - Selective installation (`--only`, `--skip`)
+   - Configuration file support (`~/.dotfiles.env`)
+   - Automatic backups and rollback on failure
+   - Update script (`./update.sh`)
+   - Uninstall script (`./uninstall.sh`)
+   - Package validation (`./scripts/validate-packages.sh`)
+
+5. **Testing & CI**
+   - **Old**: No automated testing
+   - **New**: ShellCheck, integration tests, Docker tests, GitHub Actions CI
+
+## Breaking Changes
+
+### 1. Installation Command Location
+
+**Old**:
+```bash
+./install.sh  # Monolithic script in root
+```
+
+**New**:
+```bash
+./install.sh  # Wrapper that calls scripts/install.sh
+# Or directly:
+./scripts/install.sh
+```
+
+**Impact**: Minimal - root wrapper maintained for backward compatibility
+
+### 2. Package Management
+
+**Old**:
+```bash
+# Single Brewfile
+brew bundle dump --force
+```
+
+**New**:
+```bash
+# Multiple package files
+echo "package" >> packages/common.txt
+./scripts/validate-packages.sh
+```
+
+**Impact**: Moderate - see [Brewfile to Packages Migration](#brewfile-to-packages-migration)
+
+### 3. Environment Variables
+
+**New variables** available:
+- `$OS` - Detected operating system (macos, linux, wsl)
+- `$DISTRO` - Linux distribution (ubuntu, fedora, arch, etc.)
+- `$ARCH` - Architecture (x86_64, arm64, aarch64)
+- `$IS_WSL` - WSL detection flag
+
+**Impact**: Minimal - backward compatible
+
+### 4. Component Installation
+
+**Old**:
+```bash
+# All components installed by default
+./install.sh
+```
+
+**New**:
+```bash
+# Interactive component selection
+./install.sh
+
+# Or selective installation
+./install.sh --only shell,neovim,tmux
+./install.sh --skip lua,rust
+```
+
+**Impact**: Positive - more control over what gets installed
+
+### 5. Configuration Files
+
+**Old**:
+```bash
+# No configuration file support
+# All settings via prompts
+```
+
+**New**:
+```bash
+# Optional configuration file
+~/.dotfiles.env
+```
+
+**Impact**: Positive - can automate installation
+
+### 6. Shell Theme
+
+**macOS**: No change - still uses Powerlevel10k
+
+**Linux/WSL**: Now uses **Starship** instead of attempting Powerlevel10k
+
+**Impact**: Moderate for Linux users - may need to reconfigure prompt preferences
+
+## Before You Migrate
+
+### 1. Backup Your Current Setup
+
+**Critical**: Always backup before migrating!
+
+```bash
+# Backup entire dotfiles directory
+cp -r ~/.dotfiles ~/.dotfiles.backup.v1
+tar -czf ~/dotfiles-backup-$(date +%Y%m%d).tar.gz ~/.dotfiles
+
+# Backup important configs
+cp ~/.zshrc ~/.zshrc.backup
+cp ~/.tmux.conf ~/.tmux.conf.backup
+cp ~/.config/nvim ~/.config/nvim.backup -r
+```
+
+### 2. Note Your Customizations
+
+Document any custom changes you've made:
+
+```bash
+# Check for uncommitted changes
+cd ~/.dotfiles
+git status
+git diff
+
+# Note any custom packages in Brewfile
+diff Brewfile <(brew bundle dump --file=/dev/stdout)
+```
+
+### 3. Check Disk Space
+
+Ensure sufficient space for backups:
+
+```bash
+df -h ~
+# Need at least 1GB free
+```
+
+### 4. Review Prerequisites
+
+Ensure you have required tools:
+
+```bash
+# macOS
+xcode-select -p
+
+# Linux
+git --version
+curl --version
+```
+
+## Migration Steps
+
+### Step 1: Backup (Required)
+
+```bash
+# Navigate to dotfiles
+cd ~/.dotfiles
+
+# Create backup
+cp -r ~/.dotfiles ~/.dotfiles.backup.v1
+
+# Note current commit
+git log -1 --oneline > ~/dotfiles-migration-commit.txt
+```
+
+### Step 2: Pull Latest Changes
+
+```bash
+# Fetch latest version
+git fetch origin
+
+# Checkout main branch
+git checkout main
+
+# Pull latest (v2.0.0)
+git pull origin main
+```
+
+### Step 3: Review Changes
+
+```bash
+# See what changed
+git log --oneline $(cat ~/dotfiles-migration-commit.txt | cut -d' ' -f1)..HEAD
+
+# Preview new structure
+tree -L 2 packages/
+tree -L 2 scripts/
+```
+
+### Step 4: Dry-Run Installation
+
+**Important**: Always dry-run first!
+
+```bash
+# Preview what would be installed
+./install.sh --dry-run
+
+# Preview with specific components only
+./install.sh --only shell,neovim --dry-run
+```
+
+### Step 5: Run Migration
+
+#### Option A: Full Installation (Recommended)
+
+```bash
+# Run new installer
+./install.sh
+
+# Follow interactive prompts
+# Select components you want
+```
+
+#### Option B: Non-Interactive
+
+```bash
+# Use defaults, no prompts
+./install.sh --non-interactive
+```
+
+#### Option C: Selective Installation
+
+```bash
+# Install only specific components
+./install.sh --only shell,neovim,tmux,volta,stow
+
+# Or skip components you don't want
+./install.sh --skip lua,rust,claude
+```
+
+### Step 6: Migrate Brewfile (macOS Only)
+
+If you have custom packages in your Brewfile:
+
+```bash
+# Run migration script
+./scripts/migrate-brewfile.sh
+
+# This will:
+# - Read your current Brewfile
+# - Map packages to new package files
+# - Report any unmapped packages
+# - Show suggested package file locations
+```
+
+**Manually review** the migration:
+
+```bash
+# Check what got migrated
+diff Brewfile packages/macos/core.txt
+cat packages/macos/gui-apps.txt
+cat packages/macos/fonts.txt
+
+# Add any missing custom packages
+echo "my-custom-package" >> packages/macos/core.txt
+```
+
+### Step 7: Validate Configuration
+
+```bash
+# Validate package consistency
+./scripts/validate-packages.sh
+
+# Check for conflicts
+stow -n -v -R -t ~ -d "$DOTFILES" files
+```
+
+### Step 8: Test Installation
+
+```bash
+# Reload shell
+exec zsh
+
+# Test commands
+nvim --version
+tmux -V
+volta --version
+git --version
+
+# Check dotfiles are symlinked
+ls -la ~/. | grep "\.dotfiles"
+```
+
+### Step 9: Verify Everything Works
+
+**Test checklist**:
+- [ ] Shell starts without errors
+- [ ] Neovim opens and plugins load
+- [ ] Tmux starts and plugins work
+- [ ] Git configured correctly
+- [ ] Volta/Node.js available
+- [ ] Custom aliases/functions work
+- [ ] Terminal theme looks correct
+
+## Brewfile to Packages Migration
+
+### Understanding the New Structure
+
+**Old**: Single `Brewfile`
+```ruby
+# Brewfile
+brew "git"
+brew "neovim"
+cask "ghostty"
+cask "font-meslo-lg-nerd-font"
+```
+
+**New**: Multiple package files
+```
+packages/
+├── common.txt         # git, neovim (cross-platform)
+├── macos/
+│   ├── core.txt      # macOS-specific CLI tools
+│   ├── gui-apps.txt  # ghostty (GUI apps)
+│   └── fonts.txt     # font-meslo-lg-nerd-font
+```
+
+### Automated Migration
+
+```bash
+# Run migration script
+./scripts/migrate-brewfile.sh
+
+# Review output
+# - Shows where each package was categorized
+# - Reports unmapped packages
+# - Suggests manual additions
+```
+
+### Manual Migration
+
+If you prefer manual control:
+
+#### 1. Export Current Packages
+
+```bash
+# Get current Homebrew packages
+brew leaves > ~/brew-packages.txt
+brew list --cask > ~/brew-casks.txt
+```
+
+#### 2. Categorize Packages
+
+**Cross-platform CLI tools** → `packages/common.txt`:
+```bash
+# Examples: git, neovim, fzf, ripgrep
+# These should work on Linux too
+```
+
+**macOS-only CLI tools** → `packages/macos/core.txt`:
+```bash
+# Examples: m-cli, trash, mas
+# These are macOS-specific
+```
+
+**GUI applications** → `packages/macos/gui-apps.txt`:
+```bash
+# Examples: ghostty, alacritty, visual-studio-code
+# These are Homebrew casks
+```
+
+**Fonts** → `packages/macos/fonts.txt`:
+```bash
+# Examples: font-meslo-lg-nerd-font
+# These are font casks
+```
+
+**Window managers** → `packages/macos/macos-only.txt`:
+```bash
+# Examples: yabai, skhd, sketchybar
+# macOS-specific system tools
+```
+
+#### 3. Add Custom Packages
+
+```bash
+# Add your custom packages to appropriate files
+echo "my-custom-tool" >> packages/macos/core.txt
+echo "my-custom-app" >> packages/macos/gui-apps.txt
+```
+
+#### 4. Validate
+
+```bash
+./scripts/validate-packages.sh
+```
+
+### Keeping Brewfile Temporarily
+
+The old `Brewfile` is **kept for backward compatibility** during the transition:
+
+```bash
+# You can still use Brewfile
+brew bundle install
+
+# But new system is recommended
+./install.sh --only homebrew --force
+```
+
+**Deprecation timeline**:
+- **v2.0.0 - v2.2.0**: Brewfile kept, both systems work
+- **v2.3.0+**: Brewfile will be removed (planned)
+
+## Configuration Changes
+
+### Configuration File Support
+
+**New**: Create `~/.dotfiles.env` to set defaults:
+
+```bash
+# Example ~/.dotfiles.env
+SKIP_COMPONENTS="rust,lua"
+ONLY_COMPONENTS="shell,neovim"
+NON_INTERACTIVE=true
+BACKUP_DIR="$HOME/.config/dotfiles-backups"
+```

+
+### Platform Detection
+
+The new system auto-detects your platform:
+
+```bash
+# In .zshrc, configs, etc.
+if [[ "$OS" == "macos" ]]; then
+    # macOS-specific config
+elif [[ "$OS" == "linux" ]]; then
+    # Linux-specific config
+fi
+```
+
+### Conditional Stowing
+
+Platform-specific configs are automatically skipped:
+
+- **macOS**: yabai, skhd, sketchybar configs are used
+- **Linux**: i3, rofi configs are used (if present)
+- **WSL**: Desktop environment configs are skipped
+
+## Rollback Instructions
+
+If something goes wrong, you can rollback to the old version.
+
+### Quick Rollback
+
+```bash
+# Stop if something breaks
+cd ~/.dotfiles
+
+# Restore backup
+rm -rf ~/.dotfiles
+mv ~/.dotfiles.backup.v1 ~/.dotfiles
+
+# Restore configs
+cp ~/.zshrc.backup ~/.zshrc
+cp ~/.tmux.conf.backup ~/.tmux.conf
+
+# Reload shell
+exec zsh
+```
+
+### Detailed Rollback
+
+#### 1. Restore Dotfiles Repository
+
+```bash
+cd ~/.dotfiles
+
+# Find commit before migration
+git log --oneline
+# Note the commit hash before v2.0.0
+
+# Reset to old version
+git reset --hard <commit-hash>
+
+# Or restore from backup
+cd ~
+rm -rf ~/.dotfiles
+mv ~/.dotfiles.backup.v1 ~/.dotfiles
+```
+
+#### 2. Restore Symlinks
+
+```bash
+# Remove new symlinks
+cd ~/.dotfiles
+stow -D -t ~ -d "$DOTFILES" files
+
+# Restore old symlinks (if different)
+stow -R -t ~ -d "$DOTFILES" files
+```
+
+#### 3. Restore Packages
+
+```bash
+# macOS: Use old Brewfile
+cd ~/.dotfiles
+brew bundle install
+
+# Clean up any v2.0.0 packages
+# (optional, only if you want to remove new packages)
+```
+
+#### 4. Verify Rollback
+
+```bash
+# Check git version
+cd ~/.dotfiles
+git log -1 --oneline
+
+# Test shell
+exec zsh
+
+# Test commands
+nvim --version
+tmux -V
+```
+
+### Reporting Issues

+If you had to rollback, please report the issue:
+
+```bash
+# Include:
+# - OS and version
+# - Error messages
+# - Steps that led to the problem
+# - Contents of ~/.dotfiles-install.log (if exists)

+
+## Troubleshooting
+
+### Issue: "Command not found" after migration
+
+**Solution**:
+```bash
+# Reload shell configuration
+exec zsh
+
+# Or source manually
+source ~/.zshrc
+
+# Check PATH
+echo $PATH
+```
+
+### Issue: Stow conflicts
+
+**Symptom**: `WARNING! stowing files would cause conflicts`
+
+**Solution**:
+```bash
+# Backup conflicting files
+mv ~/.zshrc ~/.zshrc.old
+mv ~/.tmux.conf ~/.tmux.conf.old
+
+# Re-run stow
+./install.sh --only stow --force
+```
+
+### Issue: Missing packages after migration
+
+**Symptom**: Some tools not installed
+
+**Solution**:
+```bash
+# Check what packages were migrated
+./scripts/validate-packages.sh
+
+# Manually add missing packages
+echo "missing-package" >> packages/macos/core.txt
+
+# Reinstall
+./install.sh --only homebrew --force
+```
+
+### Issue: Brewfile migration fails
+
+**Symptom**: `migrate-brewfile.sh` reports errors
+
+**Solution**:
+```bash
+# Manual migration
+# 1. List current packages
+brew leaves > ~/packages.txt
+
+# 2. Categorize manually
+# 3. Add to appropriate package files
+
+# 4. Validate
+./scripts/validate-packages.sh
+```
+
+### Issue: Neovim plugins broken
+
+**Symptom**: Neovim errors on startup
+
+**Solution**:
+```bash
+# Remove plugin cache
+rm -rf ~/.local/share/nvim
+rm -rf ~/.local/state/nvim
+
+# Reinstall plugins
+nvim --headless "+Lazy! sync" +qa
+
+# Or use setup component
+./install.sh --only neovim --force
+```
+
+### Issue: Tmux plugins missing
+
+**Symptom**: Tmux plugins not loading
+
+**Solution**:
+```bash
+# Reinstall TPM
+./install.sh --only tmux --force
+
+# Install plugins
+tmux
+# Press: Ctrl-b + I (capital I)
+```
+
+### Issue: Shell theme broken
+
+**Symptom**: Prompt looks wrong
+
+**macOS**:
+```bash
+# Reconfigure Powerlevel10k
+p10k configure
+```
+
+**Linux/WSL**:
+```bash
+# Check Starship config
+cat ~/.config/starship.toml
+
+# Reinstall Starship
+curl -sS https://starship.rs/install.sh | sh
+```
+
+## FAQ
+
+### Q: Do I need to migrate?
+
+**A**: Not immediately, but recommended for:
+- Cross-platform support
+- New features (dry-run, selective install, etc.)
+- Better error handling and reliability
+- Future updates and improvements
+
+### Q: Can I keep using the old Brewfile?
+
+**A**: Yes, for now. Brewfile is kept for backward compatibility but will be deprecated in a future version (v2.3.0+).
+
+### Q: Will my customizations be lost?
+
+**A**: No, if you:
+1. Backup before migrating
+2. Review your custom changes (`git status`, `git diff`)
+3. Re-apply customizations after migration
+4. Add custom packages to new package files
+
+### Q: How long does migration take?
+
+**A**:
+- Dry-run: 1-2 minutes
+- Full migration: 10-30 minutes
+- With manual package review: 30-60 minutes
+
+### Q: Can I migrate incrementally?
+
+**A**: Yes! Use selective installation:
+
+```bash
+# Migrate shell first
+./install.sh --only shell
+
+# Then neovim
+./install.sh --only neovim
+
+# Continue with other components
+./install.sh --only tmux,volta,stow
+```
+
+### Q: What if I'm on Linux, not macOS?
+
+**A**: Great! The new system fully supports Linux:
+
+```bash
+# Ubuntu
+./install.sh --non-interactive
+
+# Fedora
+./install.sh --non-interactive
+
+# Arch
+./install.sh --non-interactive
+```
+
+Packages will be installed via apt/dnf/pacman automatically.
+
+### Q: Will this break my current setup?
+
+**A**: Not if you:
+1. Backup first
+2. Use dry-run mode
+3. Test before committing
+4. Follow rollback instructions if needed
+
+The installer creates automatic backups before overwriting configs.
+
+### Q: Can I use v2.0.0 on multiple machines?
+
+**A**: Yes! That's one of the benefits:
+
+```bash
+# Machine 1 (macOS)
+./install.sh --non-interactive
+
+# Machine 2 (Linux)
+./install.sh --non-interactive
+
+# Same dotfiles, different platform detection
+```
+
+### Q: Where can I get help?
+
+**A**:
+- Check this migration guide
+- Read `README.md` for usage
+- Check `CLAUDE.md` for detailed architecture
+- Open GitHub issue for bugs
+- Check existing issues for solutions
+
+## Success Checklist
+
+After migration, verify these are working:
+
+- [ ] Shell starts without errors
+- [ ] Prompt theme displays correctly

+## 🔄 Usage
+
+### Managing Dotfiles
+
+```bash
+# Apply/update symlinks (after editing files in files/)
+sync
+
+# Remove symlinks
+unsync
+```
+
+**Important**: All configuration files live in `files/` and are symlinked to `$HOME`. Always edit files in `files/.config/` or `files/`, never the symlinked versions in `$HOME`.
+
+### Updating Dotfiles
+
+```bash
+# Pull latest changes and re-apply
+./update.sh
+
+# Update without updating packages
+./update.sh --no-packages
+
+# Preview update without executing
+./update.sh --dry-run
+```
+
+### Uninstalling
+
+```bash
+# Remove dotfile symlinks only
+./uninstall.sh
+
+# Remove symlinks and installed packages
+./uninstall.sh --remove-packages
+
+# Preview what would be removed
+./uninstall.sh --dry-run
+```
+
+### Adding New Packages
+
+**Cross-platform tools**:
+```bash
+# Add to packages/common.txt
+echo "newtool" >> packages/common.txt
+
+# Add platform-specific name mappings if needed
+echo "newtool=newtool-bin" >> packages/mappings/common-to-ubuntu.map
+
+# Validate
+./scripts/validate-packages.sh
+
+# Install
+./scripts/install.sh --only homebrew --force
+```
+
+**Platform-specific tools**:
+```bash
+# macOS
+echo "package-name" >> packages/macos/core.txt
+
+# Linux
+echo "package-name" >> packages/linux/core.txt
+
+# Reinstall packages
+./scripts/install.sh --only homebrew --force
+```
+
+### Testing Changes
+
+```bash
+# Run ShellCheck on all scripts
+./scripts/test-shellcheck.sh
+
+# Run integration tests
+./scripts/test-integration.sh
+
+# Test in Docker (Ubuntu)
+./test/test-docker.sh ubuntu --build
+```
+
+## 🛠️ Configuration
+
+### Configuration File
+
+Create `~/.dotfiles.env` to set default options:
+
+```bash
+# Skip specific components
+SKIP_COMPONENTS="rust,lua"
+
+# Install only specific components
+ONLY_COMPONENTS="shell,neovim"
+
+# Custom backup location
+BACKUP_DIR="$HOME/.config/dotfiles-backups"
+
+# Non-interactive mode
+NON_INTERACTIVE=true
+
+# Dry-run mode
+DRY_RUN=true
+
+# Force reinstall
+FORCE_INSTALL=true
+```
+
+See `.dotfiles.env.example` for all available options.
+
+### Platform-Specific Configuration
+
+The dotfiles automatically detect your platform and apply the appropriate configuration:
+
+- **macOS**: Uses Homebrew, Powerlevel10k theme, yabai/skhd window management
+- **Linux**: Uses apt/dnf/pacman, Starship prompt, optional i3/sway
+- **WSL**: Uses distro package manager, Starship prompt, Windows interop
+
+## 🐛 Troubleshooting
+
+### Common Issues
+
+**"Command not found" after installation**:
+```bash
+# Reload shell configuration
+exec zsh
+```
+
+**Stow conflicts**:
+```bash
+# Backup and remove conflicting files
+mv ~/.zshrc ~/.zshrc.backup
+mv ~/.tmux.conf ~/.tmux.conf.backup
+
+# Re-run stow
+./install.sh --only stow --force
+```
+
+**Homebrew not in PATH (macOS)**:
+```bash
+# Intel Macs
+echo 'eval "$(/usr/local/bin/brew shellenv)"' >> ~/.zprofile
+
+# ARM Macs (M1/M2/M3)
+echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
+
+# Reload
+source ~/.zprofile
+```
+
+**Permission denied errors (Linux)**:
+```bash
+# Ensure scripts are executable
+chmod +x install.sh update.sh uninstall.sh
+chmod +x scripts/*.sh
+```
+
+**Neovim version too old (Linux)**:
+```bash
+# Ubuntu: Add Neovim PPA
+sudo add-apt-repository ppa:neovim-ppa/unstable
+sudo apt update
+sudo apt install neovim
+
+# Fedora: Use copr
+sudo dnf copr enable agriffis/neovim-nightly
+sudo dnf install neovim
+
+# Arch: Use pacman
+sudo pacman -S neovim
+```
+
+**WSL systemd not working**:
+```bash
+# Enable systemd in /etc/wsl.conf
+echo "[boot]" | sudo tee /etc/wsl.conf
+echo "systemd=true" | sudo tee -a /etc/wsl.conf
+
+# Restart WSL
+wsl.exe --shutdown
+# Then reopen WSL
+```
+
+### Getting Help
+
+```bash
+# Show help
+./install.sh --help
+
+# Check version

+
+## Distribution-Specific Notes
+
+### Ubuntu/Debian
+
+**PPAs for newer software**:
+```bash
+# Neovim (latest stable)
+sudo add-apt-repository ppa:neovim-ppa/stable
+sudo apt-get update
+sudo apt-get install neovim
+
+# Zsh (latest)
+sudo add-apt-repository ppa:zsh-users/zsh
+sudo apt-get update
+sudo apt-get install zsh
+```
+
+**Package name differences**:
+- `fd` → `fd-find`
+- `bat` → `batcat`
+
+**Create aliases** if needed:
+```bash
+# Add to ~/.zshrc
+alias fd='fd-find'
+alias bat='batcat'
+```
+
+### Fedora/RHEL
+
+**Enable EPEL** (RHEL/Rocky/Alma):
+```bash
+sudo dnf install -y epel-release
+```
+
+**Copr repositories** (like PPAs):
+```bash
+# Neovim nightly
+sudo dnf copr enable agriffis/neovim-nightly
+sudo dnf install neovim
+```
+
+**DNF config optimization**:
+```bash
+# Edit /etc/dnf/dnf.conf
+sudo tee -a /etc/dnf/dnf.conf <<EOF
+fastestmirror=True
+max_parallel_downloads=10
+defaultyes=True
+EOF
+```
+
+### Arch Linux
+
+**AUR packages** (requires yay or another AUR helper):
+```bash
+# Install yay
+git clone https://aur.archlinux.org/yay.git
+cd yay
+makepkg -si
+
+# Install AUR packages
+yay -S package-name
+```
+
+**pacman configuration**:
+```bash
+# Enable parallel downloads
+# Edit /etc/pacman.conf
+# Uncomment: ParallelDownloads = 5
+
+# Enable color output
+# Uncomment: Color
+
+# Enable verbose package lists
+# Uncomment: VerbosePkgLists
+```
+
+## Troubleshooting
+
+### Shell Not Changed to zsh
+
+**Issue**: Login shell still bash after installation
+
+**Solution**:
+```bash
+# Check available shells
+cat /etc/shells
+
+# Ensure zsh is listed
+# If not:
+which zsh | sudo tee -a /etc/shells
+
+# Change shell
+chsh -s $(which zsh)
+
+# Logout and login again
+```
+
+### Font Not Showing in Terminal
+
+**Issue**: Nerd Font icons not displaying
+
+**Solution**:
+```bash
+# Verify font installation
+fc-list | grep -i "nerd font"
+
+# Refresh font cache
+fc-cache -fv
+
+# Set terminal font to Nerd Font
+# Edit terminal preferences/config
+
+# Restart terminal
+```
+
+### Package Not Found
+
+**Issue**: Package name not found during installation
+
+**Ubuntu/Debian**:
+```bash
+# Update package list
+sudo apt-get update
+
+# Search for package
+apt-cache search package-name
+```
+
+**Fedora**:
+```bash
+# Search for package
+dnf search package-name
+
+# Check if EPEL needed
+sudo dnf install epel-release
+```
+
+**Arch**:
+```bash
+# Search official repos
+pacman -Ss package-name
+
+# Search AUR
+yay -Ss package-name
+```
+
+### Permission Denied Errors
+
+**Issue**: Can't write to certain directories
+
+**Solution**:
+```bash
+# Ensure ~/.local/bin exists and is writable
+mkdir -p ~/.local/bin
+chmod 755 ~/.local/bin
+
+# For system-wide installs, use sudo
+sudo apt-get install package-name
+
+# For user installs, use appropriate flags
+pip install --user package-name
+cargo install --root ~/.local package-name
+```
+
+### Neovim Version Too Old
+
+**Ubuntu/Debian**:
+```bash
+# Add Neovim PPA
+sudo add-apt-repository ppa:neovim-ppa/stable
+sudo apt-get update
+sudo apt-get install neovim
+```
+
+**Fedora**:
+```bash
+# Use Copr
+sudo dnf copr enable agriffis/neovim-nightly
+sudo dnf install neovim
+```
+
+**Arch**:
+```bash
+# Install from official repos (usually latest)
+sudo pacman -S neovim
+
+# Or build from source
+git clone https://github.com/neovim/neovim.git
+cd neovim
+make CMAKE_BUILD_TYPE=Release
+sudo make install
+```
+
+### systemd User Services
+
+**Issue**: User services not starting automatically
+
+**Solution**:
+```bash
+# Enable lingering (allows user services when not logged in)
+sudo loginctl enable-linger $USER
+
+# Start service
+systemctl --user start service-name
+
+# Enable service
+systemctl --user enable service-name
+
+# Check status
+systemctl --user status service-name
+```
+
+## Performance Tips
+
+### Optimize Package Manager
+
+**Ubuntu/Debian**:
+```bash
+# Use apt-fast for parallel downloads
+sudo add-apt-repository ppa:apt-fast/stable
+sudo apt-get update
+sudo apt-get install apt-fast
+```
+
+**Fedora**:
+```bash
+# Edit /etc/dnf/dnf.conf
+fastestmirror=True
+max_parallel_downloads=10
+```
+
+**Arch**:
+```bash
+# Edit /etc/pacman.conf
+# Uncomment: ParallelDownloads = 5
+```
+
+### Optimize Shell Startup
+
+```bash
+# Profile zsh startup time
+time zsh -i -c exit
+
+# Disable unused zap plugins in ~/.zshrc
+# Comment out plugins you don't use
+
+# Use Starship (fast, Rust-based)
+# Already default on Linux
+```
+
+### Reduce Memory Usage
+
+```bash
+# Check memory usage
+free -h
+
+# Disable unused services
+systemctl --user disable unused-service
+
+# Use lighter alternatives
+# - i3 instead of GNOME/KDE
+# - Alacritty instead of GNOME Terminal
+# - fish/zsh instead of bash
+```
+
+## Linux-Specific Tips
+
+### Clipboard Integration
+
+**X11**:
+```bash
+# Install xclip
+sudo apt-get install xclip  # Ubuntu
+sudo dnf install xclip      # Fedora
+sudo pacman -S xclip        # Arch
+
+# Use in scripts
+echo "text" | xclip -selection clipboard
+```
+
+**Wayland**:
+```bash
+# Install wl-clipboard
+sudo apt-get install wl-clipboard  # Ubuntu
+sudo dnf install wl-clipboard      # Fedora
+sudo pacman -S wl-clipboard        # Arch
+
+# Use in scripts
+echo "text" | wl-copy
+```
+
+### Desktop Integration
+
+**Create .desktop files** for custom apps:
+
+```bash
+# Location
+~/.local/share/applications/custom-app.desktop
+
+# Example content
+[Desktop Entry]
+Type=Application
+Name=Custom App
+Exec=/path/to/app
+Icon=/path/to/icon.png
+Terminal=false
+Categories=Development;
+```
+
+### Terminal Multiplexer
+
+**tmux** recommended for headless servers:
+
+```bash
+# Start tmux
+tmux
+
+# Create session
+tmux new -s work
+
+# Attach to session
+tmux attach -t work
+
+# List sessions
+tmux ls
+```

+
+## Performance Tips
+
+### Optimize Homebrew
+
+```bash
+# Disable analytics
+brew analytics off
+
+# Cleanup old versions regularly
+brew cleanup
+
+# Use shallow clones
+export HOMEBREW_NO_GITHUB_API=1
+```
+
+### Optimize Shell Startup
+
+```bash
+# Profile zsh startup
+time zsh -i -c exit
+
+# Disable unused plugins in .zshrc
+# Comment out plugins you don't use
+
+# Use instant prompt (Powerlevel10k)
+# Already enabled by default
+```
+
+### Optimize yabai
+
+```bash
+# Reduce yabai polling
+# Edit ~/.config/yabai/yabairc
+# Comment out unnecessary signals
+```
+
+### Reduce Memory Usage
+
+```bash
+# Disable unused services
+brew services stop unused-service
+
+# Quit unused apps
+osascript -e 'quit app "AppName"'
+
+# Check memory usage
+top -o MEM
+```
+
+## macOS-Specific Tips
+
+### Mission Control Integration
+
+**yabai spaces** integrate with Mission Control:
+- Create spaces in Mission Control
+- yabai uses existing spaces
+- Use `alt + 1-9` to switch spaces (via skhd)
+
+### Keyboard Shortcuts
+
+**System-wide** (via skhd):
+- Focus window: `alt + h/j/k/l`
+- Move window: `shift + alt + h/j/k/l`
+- Switch space: `alt + 1-9`
+- Float window: `shift + alt + space`
+- Fullscreen: `alt + f`
+
+### Spotlight Alternative
+
+Use **Alfred** or **Raycast** with dotfiles:
+```bash
+# Install Alfred
+brew install --cask alfred
+
+# Or Raycast
+brew install --cask raycast
+```
+
+### Terminal Emulator Recommendations
+
+**Best for macOS**:
+1. **Ghostty** - Fast, native, GPU-accelerated
+2. **Alacritty** - Cross-platform, GPU-accelerated
+3. **Kitty** - Feature-rich, GPU-accelerated
+4. **WezTerm** - Lua-configurable, feature-rich
+
+All configured in `files/.config/`

+```
+
+**Important**: Work on files in WSL file system for best performance!
+- ✅ Good: `/home/user/project`
+- ❌ Slow: `/mnt/c/Users/user/project`
+
+### Windows Executables
+
+**Call Windows executables from WSL**:
+```bash
+# PowerShell
+powershell.exe Get-Date
+
+# CMD
+cmd.exe /c dir
+
+# VS Code (if installed on Windows)
+code.exe .
+
+# Windows Terminal
+wt.exe
+```
+
+**Path integration**:
+```bash
+# Windows PATH is automatically appended to WSL PATH
+# Check Windows executables in PATH:
+echo $PATH | tr ':' '\n' | grep -i mnt/c
+
+# Disable if needed (in /etc/wsl.conf):
+# [interop]
+# appendWindowsPath=false
+```
+
+## Performance Optimization
+
+### File System Performance
+
+**Best practices**:
+1. **Work in WSL file system** (`/home/user/`), not Windows FS (`/mnt/c/`)
+2. **Exclude WSL directories** from Windows Defender
+3. **Use WSL2** for better overall performance
+
+**Exclude from Windows Defender**:
+```powershell
+# Windows PowerShell (as Administrator)
+
+# Exclude WSL file system
+Add-MpPreference -ExclusionPath "C:\Users\YourUsername\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu22.04LTS_79rhkp1fndgsc\LocalState\ext4.vhdx"
+
+# Or exclude entire WSL directory
+Add-MpPreference -ExclusionPath "%USERPROFILE%\AppData\Local\Packages\"
+```
+
+### Memory Management
+
+**WSL2 memory usage** (in `.wslconfig`):
+```ini
+[wsl2]
+# Limit memory (default: 50% of total RAM)
+memory=8GB
+
+# Limit swap
+swap=2GB
+
+# Reclaim memory aggressively
+vmIdleTimeout=60000  # 60 seconds
+```
+
+**Reclaim memory manually**:
+```bash
+# Drop caches
+sudo sh -c "echo 3 > /proc/sys/vm/drop_caches"
+```
+
+### Network Performance
+
+**DNS configuration**:
+```bash
+# If DNS is slow, use custom DNS
+# Edit /etc/wsl.conf
+sudo tee -a /etc/wsl.conf <<EOF
+[network]
+generateResolvConf=false
+EOF
+
+# Set custom DNS in /etc/resolv.conf
+sudo tee /etc/resolv.conf <<EOF
+nameserver 8.8.8.8
+nameserver 8.8.4.4
+EOF
+
+# Prevent overwrite
+sudo chattr +i /etc/resolv.conf
+
+# Restart WSL
+```
+
+### Disk Space
+
+**Compact WSL2 virtual disk**:
+```powershell
+# Windows PowerShell (as Administrator)
+
+# Shutdown WSL
+wsl --shutdown
+
+# Compact disk image
+diskpart
+
+# In diskpart:
+# select vdisk file="C:\Users\YourUsername\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu22.04LTS_79rhkp1fndgsc\LocalState\ext4.vhdx"
+# compact vdisk
+# exit
+```
+
+## Troubleshooting
+
+### WSL Won't Start
+
+**Issue**: WSL fails to start or hangs
+
+**Solution**:
+```powershell
+# Windows PowerShell (as Administrator)
+
+# Restart WSL service
+Restart-Service LxssManager
+
+# Or restart WSL
+wsl --shutdown
+wsl
+
+# If still failing, unregister and reinstall
+wsl --unregister Ubuntu
+# Reinstall from Microsoft Store
+```
+
+### systemd Not Working
+
+**Issue**: `systemctl` commands fail
+
+**WSL2 solution**:
+```bash
+# Enable systemd in /etc/wsl.conf
+sudo tee /etc/wsl.conf <<EOF
+[boot]
+systemd=true
+EOF
+
+# Restart WSL
+exit  # From WSL
+wsl --shutdown  # From PowerShell
+wsl  # Restart
+```
+
+**WSL1**: systemd not supported, use alternatives:
+```bash
+# Use service command instead
+sudo service docker start  # Instead of systemctl start docker
+```
+
+### Network/DNS Issues
+
+**Issue**: Can't resolve hostnames or slow DNS
+
+**Solution**:
+```bash
+# Method 1: Regenerate /etc/resolv.conf
+sudo rm /etc/resolv.conf
+sudo bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf'
+sudo bash -c 'echo "nameserver 8.8.4.4" >> /etc/resolv.conf'
+
+# Method 2: Use custom DNS (permanent)
+# Edit /etc/wsl.conf
+sudo tee /etc/wsl.conf <<EOF
+[network]
+generateResolvConf=false
+EOF
+
+# Set DNS in /etc/resolv.conf
+sudo tee /etc/resolv.conf <<EOF
+nameserver 8.8.8.8
+nameserver 1.1.1.1
+EOF
+
+# Prevent overwrite
+sudo chattr +i /etc/resolv.conf
+
+# Restart WSL
+```
+
+### Clock Drift
+
+**Issue**: System time is incorrect
+
+**Solution**:
+```bash
+# Sync hardware clock
+sudo hwclock -s
+
+# Or use ntpdate
+sudo apt install ntpdate  # Ubuntu/Debian
+sudo ntpdate time.windows.com
+```
+
+### Permission Issues
+
+**Issue**: Can't access Windows files or wrong permissions
+
+**Solution**:
+```bash
+# Fix mount options in /etc/wsl.conf
+sudo tee /etc/wsl.conf <<EOF
+[automount]
+enabled=true
+options="metadata,umask=22,fmask=11"
+EOF
+
+# Restart WSL
+exit
+wsl --shutdown
+wsl
+
+# Verify
+ls -la /mnt/c/
+```
+
+### Clipboard Not Working
+
+**Issue**: `clip.exe` not found or not working
+
+**Solution**:
+```bash
+# Check if Windows PATH is appended
+echo $PATH | grep -i mnt/c
+
+# If not, enable in /etc/wsl.conf
+sudo tee -a /etc/wsl.conf <<EOF
+[interop]
+enabled=true
+appendWindowsPath=true
+EOF
+
+# Restart WSL
+
+# Test clipboard
+echo "test" | clip.exe
+```
+
+### Slow File System Performance
+
+**Issue**: File operations are slow
+
+**Solution**:
+1. **Work in WSL file system**, not `/mnt/c/`:
+   ```bash
+   # Good (fast)
+   cd ~/projects
+
+   # Bad (slow)
+   cd /mnt/c/Users/YourUsername/projects
+   ```
+
+2. **Move projects to WSL**:
+   ```bash
+   cp -r /mnt/c/Users/YourUsername/project ~/project
+   ```
+
+3. **Exclude from Windows Defender** (see [Performance Optimization](#performance-optimization))
+
+### WSL2 Memory Usage
+
+**Issue**: WSL2 using too much RAM
+
+**Solution**:
+```ini
+# Create/edit C:\Users\YourUsername\.wslconfig
+[wsl2]
+memory=4GB  # Limit memory
+swap=1GB    # Limit swap
+```
+
+**Reclaim memory**:
+```bash
+# Drop caches
+sudo sh -c "echo 3 > /proc/sys/vm/drop_caches"
+```
+
+## Tips and Tricks
+
+### Windows Terminal Integration
+
+**Install Windows Terminal**:
+```powershell
+# From Microsoft Store or via winget
+winget install Microsoft.WindowsTerminal
+```
+
+**Set WSL as default**:
+1. Open Windows Terminal
+2. Settings → Startup → Default profile → Ubuntu (or your distro)
+
+**Custom color scheme**: Edit settings.json in Windows Terminal
+
+### VS Code Integration
+
+**Install VS Code with WSL extension**:
+```bash
+# From WSL, install VS Code extension
+code .
+
+# This installs VS Code Server and integrates with Windows VS Code
+```
+
+**Open WSL project in VS Code**:
+```bash
+cd ~/project
+code .
+```
+
+### Docker Desktop Integration
+
+**Install Docker Desktop** on Windows with WSL2 backend:
+
+1. Install Docker Desktop for Windows
+2. Settings → General → Use WSL2 based engine
+3. Settings → Resources → WSL Integration → Enable for your distro
+
+**Use Docker from WSL**:
+```bash
+docker --version
+docker run hello-world
+```
+
+### Git Configuration
+
+**Git credential helper** (use Windows credentials):
+```bash
+# Use Windows Git Credential Manager
+git config --global credential.helper "/mnt/c/Program\ Files/Git/mingw64/bin/git-credential-manager.exe"
+```
+
+**Line endings**:
+```bash
+# Set line endings for cross-platform work
+git config --global core.autocrlf input
+git config --global core.eol lf
+```
+
+### SSH Agent Forwarding
+
+**Use Windows SSH agent from WSL**:
+```bash
+# Install npiperelay and socat
+sudo apt install socat  # Ubuntu/Debian
+
+# Download npiperelay (Windows)
+# https://github.com/jstarks/npiperelay
+
+# Add to ~/.zshrc
+export SSH_AUTH_SOCK=$HOME/.ssh/agent.sock
+ss -a | grep -q $SSH_AUTH_SOCK
+if [ $? -ne 0 ]; then
+    rm -f $SSH_AUTH_SOCK
+    (setsid socat UNIX-LISTEN:$SSH_AUTH_SOCK,fork EXEC:"/mnt/c/path/to/npiperelay.exe -ei -s //./pipe/openssh-ssh-agent",nofork &) >/dev/null 2>&1
+fi
+```
+
+### Accessing localhost
+
+**WSL2 networking**:
+```bash
+# Access Windows localhost from WSL2
+# Windows localhost is NOT 127.0.0.1 in WSL2
+
+# Get Windows IP
+cat /etc/resolv.conf | grep nameserver | awk '{print $2}'
+
+# Or use hostname
+export WINDOWS_HOST=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2}')
+
+# Access Windows service
+curl http://$WINDOWS_HOST:8080
+```
+
+**Access WSL from Windows**:
+```
+# Use WSL hostname (Windows 11)
+http://localhost:8080
+
+# Or WSL IP
+wsl hostname -I
+```
+
+### Backup and Restore
+
+**Export WSL distribution**:
+```powershell
+# Windows PowerShell
+wsl --export Ubuntu C:\backup\ubuntu-backup.tar
+```
+
+**Import WSL distribution**:
+```powershell
+# Windows PowerShell
+wsl --import Ubuntu C:\WSL\Ubuntu C:\backup\ubuntu-backup.tar
+```
+
+### Update WSL
+
+```powershell
+# Windows PowerShell
+wsl --update
+
+# Check version
+wsl --version
+```

+```
+
+## Package File Format
+
+Each package file is a simple text file with one package name per line:
+
+```
+# This is a comment
+git
+neovim
+fzf
+```
+
+- Lines starting with `#` are comments
+- Empty lines are ignored
+- Package names should be simple (no version specifiers)
+
+## Categories
+
+### common.txt
+Essential cross-platform CLI tools that should be available on all systems:
+- Version control (git, gh)
+- Shell utilities (bash, zsh, tmux, fzf)
+- File search (fd, ripgrep, eza)
+- Text processing (jq, grep)
+- Development tools (neovim, vim, make)
+- Programming languages (python, go)
+
+### optional.txt
+Nice-to-have tools that may not be available on all platforms:
+- Advanced CLI tools (ast-grep, chafa, viu)
+- Language servers and formatters
+- Additional terminal multiplexers (zellij)
+
+### Platform-Specific Files
+
+**macOS:**
+- `core.txt`: macOS-specific command-line tools
+- `gui-apps.txt`: GUI applications via Homebrew casks
+- `fonts.txt`: Nerd fonts and programming fonts
+- `macos-only.txt`: Window managers (yabai, skhd), status bars (sketchybar)
+- `taps.txt`: Custom Homebrew repositories
+
+**Linux:**
+- `core.txt`: Linux distribution packages
+- `gui-apps.txt`: Linux GUI applications (via apt, pacman, dnf, or Flatpak/Snap)
+
+**WSL:**
+- `wsl-specific.txt`: WSL-specific utilities and configurations
+
+## Mapping Files
+
+Mapping files handle package name differences across platforms. Format:
+
+```
+# common-package-name=platform-specific-name
+fd=fd-find
+bat=batcat
+```
+
+## Adding New Packages
+
+1. **Cross-platform tool**: Add to `common.txt`
+2. **Optional tool**: Add to `optional.txt`
+3. **Platform-specific**: Add to appropriate platform file
+4. **Name differs**: Add mapping to `mappings/common-to-*.map`
+
+## Validation
+
+Use the validator script to ensure consistency:
+
+```bash
+./scripts/validate-packages.sh
+```
+
+This will:
+- Check that all common packages have mappings for each platform
+- Report missing packages per OS
+- Show differences between platforms
+- Verify no duplicate packages
+
+## Migration from Brewfile
+
+The old `Brewfile` is kept temporarily for backward compatibility. To migrate:
+
+```bash
+./scripts/migrate-brewfile.sh
+```
+
+## Future Plans
+
+- Add Windows native support
+- Add Nix package manager support
+- Add Flatpak/Snap support for Linux GUI apps
+- Automated package updates and version management

+# Package Name Mappings
+
+This directory contains mapping files that translate package names from `common.txt` to platform-specific package names.
+
+## Purpose
+
+Different package managers use different names for the same software. For example:
+- `fd` on Homebrew/Arch = `fd-find` on Ubuntu/Debian
+- `bat` on Homebrew/Arch = `batcat` on Ubuntu/Debian
+- `gh` on Homebrew = `github-cli` on Arch
+
+These mapping files ensure the correct package names are used on each platform.
+
+## File Format
+
+Each mapping file uses a simple `key=value` format:
+
+```
+# Comments start with #
+common-package-name=platform-specific-name
+fd=fd-find
+bat=batcat
+```
+
+## Mapping Files
+
+- `common-to-macos.map` - Homebrew package names
+- `common-to-ubuntu.map` - Ubuntu/Debian (apt) package names
+- `common-to-arch.map` - Arch Linux (pacman) package names
+- `common-to-fedora.map` - Fedora/RHEL (dnf) package names
+
+## Usage
+
+The install script will:
+1. Read packages from `common.txt`
+2. Check if a mapping exists for the target platform
+3. Use the mapped name if it exists, otherwise use the common name
+4. Install the package using the appropriate package manager
+
+## Adding New Mappings
+
+When adding a package to `common.txt`, check if it has different names on other platforms:
+
+1. Look up the package name on each platform
+2. If it differs, add a mapping to the appropriate file
+3. Run `./scripts/validate-packages.sh` to verify
+
+## Examples
+
+### Ubuntu Mapping
+```bash
+# In common.txt
+fd
+
+# In common-to-ubuntu.map
+fd=fd-find
+
+# Result: installs 'fd-find' on Ubuntu
+```
+
+### Arch Mapping
+```bash
+# In common.txt
+gh
+
+# In common-to-arch.map
+gh=github-cli
+
+# Result: installs 'github-cli' on Arch
+```

+
+## Optional Future Enhancements
+
+- [ ] ⬜ Add Windows native support (PowerShell script)
+- [ ] ⬜ Add Nix package manager support
+- [ ] ⬜ Add Flatpak/Snap support for GUI apps on Linux
+- [ ] ⬜ Create web-based installer generator
+- [ ] ⬜ Add telemetry/analytics (opt-in) for installation success rates
+- [ ] ⬜ Add auto-update mechanism for dotfiles
+- [ ] ⬜ Create dotfiles sync service for multiple machines
+
+---
+
+## Notes
+
+### Package Management Approach
+
+**Why separate files instead of complex mapping?**
+- Cleaner and more maintainable
+- Acknowledges that different platforms have different apps (yabai on macOS, i3 on Linux)
+- Easier to see what's installed on each platform
+- Simple mapping files only for packages with different names
+- Validator script ensures consistency for common tools
+
+**Structure Benefits:**
+- `common.txt` = tools that SHOULD exist everywhere (git, neovim, fzf, etc.)
+- `optional.txt` = nice-to-have tools (may skip on some platforms)
+- OS-specific folders = embrace platform differences
+- Mapping files = only for name differences (fd vs fd-find)
+- Validator = ensures common tools are available on all platforms
+
+### General Notes
+
+- **Keep backward compatibility during refactoring**
+  - Keep old install.sh as install-legacy.sh during transition
+  - Use feature flags to toggle between old/new behavior
+  - Maintain Brewfile alongside new package system temporarily
+
+- **Testing strategy**
+  - Create git branches for each phase
+  - Test on macOS (Intel and ARM if possible)
+  - Test on Linux VM before proceeding
+  - Use `--dry-run` flag extensively
+
+- **VS Code extensions**
+  - Keep `scripts/vscode-extensions.txt` separate
+  - Not part of package system (different installation mechanism)
+  - Consider moving to `config/vscode/extensions.txt` for consistency
+
+- **Document breaking changes**
+  - Create CHANGELOG.md for migration notes
+  - Add migration guide for users updating from old version
+
+- **Get feedback from users testing on different platforms**
+  - Test Ubuntu, Fedora, Arch if possible
+  - Test WSL1 and WSL2
+  - Document platform-specific quirks
+
+---
+
+**Total Estimated Time**: 32-52 hours
+**Priority Order**: Phase 1 → Phase 2 → Phase 3 → Phase 4 → Phase 5 → Phase 6 → Phase 7 → Phase 9 → Phase 10 → Phase 8
+
+**Rationale for order:**
+- Phase 1-2: Fix bugs and add reliability (foundation)
+- Phase 3: Package system (needed before Linux support)
+- Phase 4: UI improvements (better UX during development)
+- Phase 5: Linux support (uses package system)
+- Phase 6: WSL support (builds on Linux support)
+- Phase 7: Restructure (consolidate all changes)
+- Phase 9: Testing (validate everything works)
+- Phase 10: Documentation (CRITICAL - update CLAUDE.md for future Claude Code sessions)
+- Phase 8: Additional features (nice-to-haves)
+
+**Note:** Phase 10 is especially important as CLAUDE.md ensures future Claude Code instances can work effectively with the new architecture.
