1. Clone this directory as your project repository
2. Set up AWS S3 bucket and credentials
3. Configure environment:

   cp .env.example .env
   # Edit .env with your AWS credentials

4. Run locally:

   pip install -r requirements.txt

This repository includes automated deployment to staging and production servers:

• Push to staging branch → Deploys to staging server
• Push to main branch → Deploys to production server

See DEPLOYMENT.md for complete setup instructions.

This example demonstrates:

✅ Multi-Environment Deployment - Separate staging and production
✅ Docker Containerization - Consistent deployment environments
✅ GitHub Actions CI/CD - Automated build and deployment
✅ SSH-based Deployment - Direct server deployment
✅ Environment Management - Secure credential handling
✅ Health Checks - Deployment verification

Perfect for learning real-world CI/CD practices!
