+# Projekt-arendehantering
+
+Spring Boot application for case management with a Thymeleaf UI, PostgreSQL, and MinIO.
+
+## Prerequisites
+
+- Java 25
+- Docker Desktop (or Docker Engine with Compose)
+- Maven Wrapper (`mvnw`) is included in the project
+
+## Start the application (local development)
+
+### 0) Verify Docker is running (Windows)
+
+Before running `docker compose up -d`, make sure Docker Desktop is started and the Linux engine is running.
+
+1. Start Docker Desktop.
+2. Wait until Docker Desktop shows **Engine running**.
+3. Verify in PowerShell:
+
+```powershell
+docker version
+```
+
+If Docker is healthy, this command prints both `Client` and `Server` sections.
+
+If you get an error like:
+
+`open //./pipe/dockerDesktopLinuxEngine: The system cannot find the file specified`
+
+it means Docker Desktop is not running (or not fully started yet). Start/restart Docker Desktop, wait 10-30 seconds, then run `docker version` again.
+
+### 1) Start infrastructure services
+
+```bash
+docker compose up -d
+```
+
+This starts:
+- PostgreSQL on `localhost:5432`
+- MinIO API on `localhost:9000`
+- MinIO Console on `localhost:9001`
+
+### 2) Start the Spring Boot application with the local profile
+
+```bash
+./mvnw spring-boot:run -Dspring-boot.run.profiles=local
+```
+
+On Windows PowerShell:
+
+```powershell
+.\mvnw spring-boot:run "-Dspring-boot.run.profiles=local"
+```
+
+### 3) Open the app
+
+- [http://localhost:8080](http://localhost:8080)
+
+## Login and access
+
+### Admin account (use normal login page)
+
+There is no separate admin login page. Use the normal login form at [http://localhost:8080/login](http://localhost:8080/login).
+
+When running with profile `local`, an admin-level account is seeded from `data-local.sql`:
+
+- Email: `admin@traumateam.com`
+- Password: `password`
+- Role: `MANAGER`
+
+Log in with:
+
+- Username/Email: `admin@traumateam.com`
+- Password: `password`
+
+### Other login options
+
+- Patients can register via `/register` and then log in with email/password at `/login`.
+- Employees can use GitHub OAuth via the "Sign in with GitHub" button on `/login`.
+
+## Stop services
+
+```bash
+docker compose down
+```
+
+## Quick troubleshooting
+
+- `docker compose up -d` fails with pipe/engine error:
+  - Start Docker Desktop and wait until the engine is green/running.
+  - Re-run `docker version` and confirm `Server` appears.
+- PostgreSQL fails with `Bind for 0.0.0.0:5432 failed: port is already allocated`:
+  - Another process (often a local PostgreSQL service) already uses port `5432`.
+  - Find what owns the port in PowerShell:
+
+```powershell
+netstat -ano | findstr :5432
+```
+
+  - Note the PID in the last column, then check process name:
+
+```powershell
+tasklist /FI "PID eq <PID>"
+```
+
+  - If it is a local PostgreSQL/service you do not need right now, stop it and retry:
+
+```powershell
+Stop-Service -Name postgresql* -ErrorAction SilentlyContinue
+docker compose up -d
+```
+
+  - If you want to keep your local PostgreSQL running, map Docker PostgreSQL to another host port:
+    1. Edit `docker-compose.yml` PostgreSQL ports from `"5432:5432"` to `"5433:5432"`.
+    2. Edit `src/main/resources/application.properties` database URL from `localhost:5432` to `localhost:5433`.
+    3. Run `docker compose up -d` again.
+- App starts but login fails:
+  - Confirm you started Spring with profile `local` so `data-local.sql` is loaded.
