+# Branch Protection and CI/CD Setup
+
+This repository implements comprehensive branch protection rules and automated quality checks.
+
+## Branch Ruleset
+
+The main branch is protected with the following rules:
+
+### Required Reviews
+- At least 1 approving review required
+- Stale reviews are dismissed when new commits are pushed
+- Review thread resolution is required before merging
+
+### Required Status Checks
+- **Code Linting**: Ensures code follows formatting standards using Black
+- **Tests**: Validates all tests pass across multiple database backends
+- **Security Scan**: Checks for security vulnerabilities using safety and bandit
+- Branches must be up to date before merging
+
+### Additional Protections
+- Force pushes are disabled
+- Branch deletion is disabled
+- Non-fast-forward updates are prevented
+- Signed commits are required
+
+## CI/CD Pipeline
+
+The repository includes automated workflows that run on:
+- Push to `main` and `develop` branches
+- Pull requests targeting `main` and `develop` branches
+
+### Workflow Jobs
+
+1. **Code Linting**
+   - Runs Black formatter in check mode
+   - Ensures consistent code formatting
+
+2. **Tests**
+   - Sets up test databases (PostgreSQL, MySQL, MongoDB)
+   - Installs dependencies
+   - Runs pytest test suite
+   - Tests against all supported database backends
+
+3. **Security Scan**
+   - Runs `safety` to check for known security vulnerabilities in dependencies
+   - Runs `bandit` to scan for common security issues in Python code
+
+## Database Support
+
+The CI pipeline tests against:
+- **PostgreSQL 15**: Running on port 5432
+- **MySQL 8.0**: Running on port 3306  
+- **MongoDB 7**: Running on port 27017
+
+## Local Development
+
+You can run the same checks locally using the provided Makefile:
+
+```bash
+# Run tests
+make test
+
+# Run linting
+make lint
+
+# Start development environment
+make up
+```
+
+## Bypass Options
+
+Organization administrators can bypass branch protection rules when necessary for emergency fixes or maintenance.
+
+## Configuration Files
+
+- `.github/workflows/ci.yml`: CI/CD pipeline configuration
+- `.github/ruleset.yml`: Branch protection ruleset definition

+
+## Reporting a Vulnerability
+
+If you discover a security vulnerability in this FastAPI application, please report it responsibly:
+
+1. **Do not** create a public GitHub issue for security vulnerabilities
+2. Email the maintainers directly or use GitHub's Security Advisories feature
+3. Include a detailed description of the vulnerability
+4. Provide steps to reproduce the issue
+5. If possible, include a suggested fix
+
+## Security Features
+
+This repository implements several security measures:
+
+### Automated Security Scanning
+- **Dependency Scanning**: Uses `safety` to check for known vulnerabilities in Python packages
+- **Code Security Analysis**: Uses `bandit` to scan for common security issues in Python code
+- **CI/CD Integration**: Security scans run automatically on all pull requests
+
+### Branch Protection
+- Required code reviews before merging
+- Automated status checks must pass
+- No force pushes to protected branches
+- Signed commits required
+
+### Development Security
+- Dependencies are pinned to specific versions
+- Regular automated dependency updates
+- Secure database connection practices
+- Input validation using Pydantic models
+
+## Security Best Practices
+
+When contributing to this project:
+
+1. **Dependencies**: Keep dependencies up to date and avoid packages with known vulnerabilities
+2. **Secrets**: Never commit secrets, API keys, or credentials to the repository
+3. **Input Validation**: Always validate and sanitize user inputs
+4. **Database Security**: Use parameterized queries to prevent SQL injection
+5. **Authentication**: Implement proper authentication and authorization mechanisms
+6. **HTTPS**: Always use HTTPS in production environments
+
+## Security Tools Used
+
+- `safety`: Python dependency vulnerability scanner
+- `bandit`: Python security linter
+- `black`: Code formatter (helps maintain consistent, readable code)
+- `pytest`: Testing framework for security test coverage
+
+## Response Timeline
+
+- **Initial Response**: Within 48 hours of report
+- **Status Update**: Within 1 week of initial response
+- **Resolution**: Varies based on complexity, but prioritized based on severity
+
+Thank you for helping keep this project secure!
