# Run linters
./scripts/dev.sh lint

# Format code
./scripts/dev.sh format
```

## 🚢 Deployment

See [Deployment Guide](./docs/DEPLOYMENT.md) for production deployment instructions.

### Basic Production Setup
1. Use environment-specific `.env` file
2. Enable SSL/TLS termination
3. Configure proper domain names
4. Set up backup procedures
5. Monitor logs and metrics

## 🔒 Security

- Application-specific access keys
- Master key for admin access
