## Configuration

### Settings Modules

The project uses different settings modules for different environments:

- `config.settings.development` - Local development
- `config.settings.production` - Production deployment
- `config.settings.selfhosted` - Self-hosted instances

Set via environment variable:
```bash
export DJANGO_SETTINGS_MODULE=config.settings.development
```

### Environment Variables

Key environment variables (see `.env.example`):

- `SECRET_KEY` - Django secret key (required in production)
- `DEBUG` - Enable debug mode (True/False)
- `ALLOWED_HOSTS` - Comma-separated list of allowed hosts
- `DATABASE_URL` - Database connection string
- `REDIS_URL` - Redis connection for Celery
- `CSRF_TRUSTED_ORIGINS` - HTTPS origins for CSRF

## API Documentation

### Authentication

The API supports both session-based and token-based authentication.

**Get Token:**
```bash
POST /api/auth/login/
{
  "email": "user@example.com",
  "password": "password"
}
```

**Use Token:**
```bash
Authorization: Bearer <token>
```

- [ ] Use PostgreSQL instead of SQLite
- [ ] Set up Redis for Celery
- [ ] Configure static file serving
- [ ] Set up SSL/TLS certificates
- [ ] Configure backup strategy
- [ ] Set up monitoring and logging

### Nginx Configuration

Example nginx config for reverse proxy:

```nginx
server {
    listen 443 ssl;
    server_name tasks.firebugit.com;

    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;

    location / {
        proxy_pass http://localhost:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /static/ {
        alias /path/to/static/;
    }
}
```

## Mobile App Integration

This server works with the KeepItGoing Android app via the sync endpoint.

**Sync Protocol:**
- Client sends current state and last sync timestamp
- Server returns updates since last sync
- Server accepts client changes
- Conflict resolution handled server-side
