+### Git Hooks
+
+We use [Lefthook](https://github.com/evilmartians/lefthook) to manage Git hooks (formatting, linting, tests). After installing lefthook (e.g., via `brew install lefthook` or `npm install -g @evilmartians/lefthook`), set up the hooks by running:
+
+```bash
+lefthook install

-**Roda** (Portuguese for "wheel") is a pure Lua terminal spinner library.
+**Roda** (Portuguese for "wheel") is an elegant terminal spinner utility. It can be used as a standalone executable in bash scripts to show progress for long-running commands, or as a pure Lua library.
 
 ## Features
 
 ![Demo](./assets/demo.gif)
 
+- **Standalone Executable** - perfect for wrapping slow commands in bash scripts
 - **16 built-in spinner styles** - dots, line, arc, bounce, and more
 - **Colorized output**     - 9 terminal colors supported
 - **Terminal states**      - succeed, fail, warn, info with symbols
 - **Dynamic text updates** - change text while spinning
 - **Highly configurable**  - intervals, colors, prefixes, suffixes
 - **Minimal dependencies** - only requires `luasystem` and `luv`
-- **Lua 5.1+ compatible**  - works with Lua 5.1, 5.2, 5.3, 5.4, and LuaJIT
-- **Asynchronous**         - non-blocking execution using `luv`
+- **Asynchronous**         - non-blocking execution

-## Quick Start
+## Usage (CLI)
+
+Use Roda to add elegant loading indicators to your bash scripts. Simply wrap your long-running commands with `roda`:
+
+```bash
+# Basic usage
+roda --title "Installing dependencies..." -- npm install
+
+# Custom spinner style
+roda --title "Waiting for database..." --spinner "dots2" -- sleep 5
+
+# Show output of the command (by default output is hidden while spinning)
+roda --show-output --title "Building project..." -- make build
+```
+
+### CLI Options
+
+| Option | Description |
+|--------|-------------|
+| `--title TEXT` | Text to display next to the spinner |
+| `--spinner NAME` | Spinner style to use (e.g., `dots`, `line`, `arc`) |
+| `--show-output` | Display the command's stdout/stderr after it finishes |
+| `--` | Separates roda options from the command to execute |
+
+## Usage (Lua Library)
+
+Roda is compatible with Lua 5.1, 5.2, 5.3, 5.4, and LuaJIT.
