 React Native Firebase cannot be used in the "Expo Go" app, because [it requires custom native code](https://docs.expo.io/workflow/customizing/).
 
 ### Expo Bare Workflow
+Where possible, it is recommended by the Expo team to use Managed Workflow.
 
 If you're using [Bare Workflow](https://docs.expo.io/introduction/managed-vs-bare/#bare-workflow), please follow the above [Android Setup](/#2-android-setup) and [iOS Setup](/#3-ios-setup) steps.
 
 ### Expo Managed Workflow
 
-Since Expo Go will not work with react-native-firebase, the suggested workflow is to use a [custom development client](https://docs.expo.dev/clients/getting-started/). If starting a new app, you can run `npx create-react-native-app -t with-dev-client` to have this set up automatically. It will also allow you to use the Expo Application Service (EAS Build) do the Android and iOS builds.
