+### ⚠️ Important: Codegen Configuration
+
+This library uses React Native's new architecture and requires proper codegen configuration in your consuming app. If you encounter build errors related to missing generated sources, please see the [TROUBLESHOOTING.md](./TROUBLESHOOTING.md) guide.
+
+**Quick fix**: Ensure your consuming app has `codegenEnabled = true` in the React configuration.
+
+**💡 Pro tip**: Run `yarn check-setup` (if you're in this repo) or use the setup check script to verify your configuration. For consuming apps, you can also run `npx react-native-biometric-login verify-setup` to check your setup.
