 ## Usage
 
-This package is [endorsed](https://flutter.dev/docs/development/packages-and-plugins/developing-packages#endorsed-federated-plugin), which means you can simply use `camera` normally. This package will be automatically included in your app when you do.
+### Depend on the package
+
+This package is not an [endorsed implementation](https://flutter.dev/docs/development/packages-and-plugins/developing-packages#endorsed-federated-plugin)
+of the google_maps_flutter plugin yet, so you'll need to [add it explicitly](https://pub.dev/packages/camera_web/install).
