   ```

2. **Access the application:**
   - Frontend: http://localhost
   - Backend API: http://localhost:8000
   - API Documentation: http://localhost:8000/docs

3. **View logs:**

## Development

To rebuild after code changes:
```bash
docker-compose up -d --build
```

To rebuild specific service:
```bash
docker-compose up -d --build backend

```

## Troubleshooting

**Check service status:**
```bash

```bash
docker-compose logs backend
```

**View frontend logs:**

docker-compose logs frontend
```

**Restart services:**
```bash
docker-compose restart
```

**Clean everything:**
```bash
docker-compose down -v
docker system prune -a
