## Database Schema Files

### Migration Files (migrations/versions/)
- Initial schema (Groups, Messages, etc)
- Add group members tracking
- Add statistics tables
- Add keyword filtering
- (+ 5-10 more migrations as needed)

Each migration is tracked by Alembic for version control.

## Configuration Files Explained

### .env.example
Template for environment variables needed for:
- Telegram credentials
- Database connection
- Redis connection
- Logging configuration
- Celery settings

### pyproject.toml
Modern Python project configuration including:
- Package metadata
- Dependencies (main & optional)
- Tool configurations (black, isort, mypy, pytest, etc)
- Build system settings

### .pre-commit-config.yaml
Automated code quality checks before git commit:
- Code formatting (black, isort)
- Linting (flake8, mypy, pylint)
- Security (bandit)
- General (trailing whitespace, merge conflicts)

## Workflow Integration

### Development Workflow
```
Edit Code → Pre-commit hooks → Commit → GitHub Actions (tests)
```

### Build Workflow
```
Push to main → GitHub Actions (build) → Docker Hub
```

### Deployment Workflow
```
docker-compose up → alembic migrate → bot ready
```

## Best Practices Implemented

✅ **Code Organization**
- Clear separation of concerns
- Models, handlers, tasks separated
- Reusable components

✅ **Configuration**
- Environment-based config
- No secrets in code
- .env.example as template

✅ **Testing & Quality**
- Unit tests included
- Integration tests
- Code coverage tracking
- Linting enforcement

✅ **Documentation**
- README with badges
- Development guide
- Production deployment guide
- Architecture documentation
- Inline code comments

✅ **Automation**
- Docker containerization
- CI/CD pipelines
- Pre-commit hooks
- Dependency updates (Renovate)
- Helper scripts

✅ **Security**
- Secrets management
- Input validation
- SQL injection protection
- Password hashing
- HTTPS support
