## Development Setup

### Prerequisites
- Node.js 18+
- Docker Desktop
- Git

### Quick Start
\`\`\`bash
# Clone repository
git clone https://github.com/company/project.git
cd project

# Run setup
npm run setup

# Start development server
npm run dev
\`\`\`

### Available Commands
- `npm run dev` - Start development server
- `npm run test` - Run tests
- `npm run lint` - Lint code
- `npm run db:migrate` - Run database migrations

### Troubleshooting
- **Port 3000 already in use**: Run `lsof -ti:3000 | xargs kill`
- **Database connection failed**: Ensure Docker is running
