+# Docker Development
+
+This setup runs the Laravel app, Vite, and MySQL through Docker Compose.
+
+## Services
+
+- Laravel app: `http://localhost:8000`
+- Vite dev server: `http://localhost:5173`
+- MySQL from host: `127.0.0.1:3307`
+- MySQL from containers: `mysql:3306`
+
+## First Run
+
+If you want Docker to own the Laravel environment values, copy the Docker example:
+
+```powershell
+Copy-Item .env.docker.example .env
+```
+
+Then start everything:
+
+```powershell
+docker compose up -d --build
+```
+
+The app container installs Composer dependencies, generates `APP_KEY` if needed, clears config, runs migrations, and seeds the database (roles + default admin account).
+
+The Vite container installs Node dependencies and starts the dev server.
+
+## Useful Commands
+
+```powershell
+docker compose ps
+docker compose logs -f app
+docker compose logs -f vite
+docker compose exec app php artisan migrate:status
+docker compose exec app php artisan test
+docker compose down
+```
+
+To remove the MySQL data volume and start with a clean database:
+
+```powershell
+docker compose down -v
+```
+
+## Database Credentials
+
+```text
+Database: webgis_miskin
+Username: webgis
+Password: secret
+Root password: root
+```
+
+## Default Login
+
+After first run, akses `http://localhost:8000` dan login dengan:
+
+```text
+Email: admin@webgis.local
+Password: admin123
+```
