+# ExoPlayer demo with Compose integration
+
+This is an experimental ExoPlayer demo app that is built fully using Compose
+features. This should be taken as Work-In-Progress, rather than experimental API
+for testing out application development with the media3 and Jetpack Compose
+libraries. Please await further announcement via Release Notes for when the
+implementation is fully integrated into the library.
+
+For an intermediate solution, use Jetpack Compose Interop with AndroidView and
+PlayerView. However, note that it provides limited functionality and some
+features may not be supported.
+
+See the [demos README](../README.md) for instructions on how to build and run
+this demo.
