+### Code Quality
+
+The project maintains code quality through automated checks that run on every pull request:
+
+1. **Linting**
+   - Runs ESLint to check code style and quality
+   - Command: `npm run lint`
+
+2. **Dependencies**
+   - Uses `npm i --legacy-peer-deps` for deterministic installations
+   - GitHub Actions cache for faster builds
+
+3. **Code Formatting**
+   - Ensures consistent code formatting
+   - Can be automatically fixed using `npm run lint:fix`
+
+4. **Testing**
+   - Unit tests using Karma
+   - Command: `npm run test`
+
+These checks ensure consistent code style and secure dependency management.
+
+### Package Publishing
