+   - Brief description of functionality
+   - Usage instructions with examples
+   - Any configuration requirements
+
+## Testing
+
+Before committing plugin changes:
+
+1. Check files are properly formatted: Run `make format`
+2. Check code style and linting: Run `make lint`
+3. Test the plugin functionality: Run `make test`
+4. Verify documentation accuracy
+5. Ensure all examples work as described
