+## Development
+
+### Testing and Quality Assurance
+
+The project uses several tools to ensure code quality:
+
+- **pytest**: For unit testing
+- **mypy**: For static type checking
+- **ruff**: For linting and code formatting
+- **pre-commit**: For automated code quality checks
+
+### Continuous Integration
+
+The project uses GitHub Actions for CI/CD with the following checks:
+
+- Code linting and formatting
+- Type checking
+- Unit tests with coverage reporting
+- Dependency updates via Dependabot
+
+### Pre-commit Hooks
+
+Before committing, ensure pre-commit hooks are installed:
+
+```bash
+pip install pre-commit
+pre-commit install
+```
+
+### Running Tests Locally
+
+```bash
+# Run tests
+pytest
+
+# Run tests with coverage
+pytest --cov=./src --cov-report=term-missing
+
+# Run type checking
+mypy src tests
+
+# Run linting
+ruff check .
