-FirebaseUI Auth is a modern, Compose-based authentication library for Firebase Authentication on Android.
+[FirebaseUI](https://github.com/firebase/firebaseui-android) Auth is a library built on top of the Firebase Authentication SDK that provides drop-in UI flows for use in your app.
 
-`10.x` is currently a beta release.
+Caution: Version 10.x is currently a **beta release**. This means that the functionality might change in backward-incompatible ways or have limited support. A beta release is not subject to any SLA or deprecation policy.

For apps that still use Activities, see [Existing Activity-based apps](#existing-activity-based-apps).
