 ## Development
 
 - Follow Dart/Flutter conventions
-- Run `flutter analyze` before submitting
+- Run `dart format .` to format your code (note: generated files like `*.g.dart` are excluded from CI checks)
+- Run `flutter analyze` before submitting to check for issues
+- Run `flutter test` if tests are available
 - Test your changes thoroughly
 
+### Code Quality Checks
+
+The project includes automated CI checks that run on all pull requests:
+
+1. **Code Formatting**: Ensures code follows Dart formatting standards
+   - Run locally: `dart format .` to format all files
+   - Note: CI only checks non-generated files (excludes `.g.dart`, `.freezed.dart`)
+   - Generated files are reformatted automatically by build tools
+
+2. **Static Analysis**: Checks for code issues and potential bugs
+   - Run locally: `flutter analyze`
+   - Note: CI excludes generated files from analysis (configured in `analysis_options.yaml`)
+
+3. **Tests**: Runs unit and widget tests (when available)
+   - Run locally: `flutter test`
+
+All these checks must pass before your changes can be merged.
+
 ## Internationalization (i18n)
 
 This project uses `slang` for internationalization with JSON files.

 ## Development
 
+### Code Quality
+
+Before submitting changes, ensure your code passes all quality checks:
+
+```bash
+# Format code (including generated files)
+dart format .
+
+# Analyze code for issues
+flutter analyze
+
+# Run tests (if available)
+flutter test
+```
+
+**Note**: CI checks exclude generated files (`.g.dart`, `.freezed.dart`) from formatting and analysis checks. You can run `dart format .` locally to format everything, but only your hand-written code will be validated in CI.
+
+These checks are automatically run in CI for all pull requests.

 ### Code Generation
 
 The project uses code generation for JSON serialization. After modifying model classes, run:
