+
+## Security Notes
+
+### For Users Upgrading
+1. **Review custom code**: If you have custom JavaScript that uses `window.curentUenc`, update it to `window.currentUenc`
+2. **Test thoroughly**: The React 18 and Webpack 5 updates may affect custom implementations
+3. **Check file permissions**: Ensure proper permissions on pub/static directories after upgrade
+4. **Review security**: See SECURITY.md for new security guidelines
+
+### For Developers
+- All new code must use Magento's RequestInterface instead of superglobals
+- Follow the security checklist in SECURITY.md before submitting PRs
+- Run security scans: `npm audit` and CodeQL before deploying
+
+## Verification
+- ✅ Code review completed with no issues
+- ✅ CodeQL security scan passed with 0 alerts
+- ✅ All unit tests updated and passing
+- ✅ No regression in functionality
+
+## Migration Guide
+
+### Updating from Previous Versions
+
+1. **Backup your installation**
+2. **Update via Composer**
+   ```bash
+   composer require genaker/react-luma
+   php bin/magento setup:upgrade
+   php bin/magento cache:clean
+   ```
+3. **Install new npm dependencies** (if building from source)
+   ```bash
+   cd vendor/genaker/magento-reactjs
+   npm install
+   npm run build
+   ```
+4. **Test your site thoroughly**
+   - Verify all React components still work
+   - Test cart, checkout, and product pages
+   - Check browser console for errors
+
