+module.
+
+For example, to depend on ExoPlayer with DASH playback support and UI components
+you can add dependencies on the modules like this:
 
 ```gradle
-implementation 'com.google.android.exoplayer:exoplayer:2.X.X'
+implementation 'androidx.media3:media3-exoplayer:1.X.X'

 ```
 
-where `2.X.X` is your preferred version.
+where `1.X.X` is your preferred version. All modules must be the same version.

+[libraries directory]: libraries
-The available library modules are listed below. Adding a dependency to the full
-ExoPlayer library is equivalent to adding dependencies on all of the library
-modules individually.
-
-* `exoplayer-core`: Core functionality (required).
-* `exoplayer-dash`: Support for DASH content.
-* `exoplayer-hls`: Support for HLS content.
-* `exoplayer-rtsp`: Support for RTSP content.
-* `exoplayer-smoothstreaming`: Support for SmoothStreaming content.
-* `exoplayer-transformer`: Media transformation functionality.
-* `exoplayer-ui`: UI components and resources for use with ExoPlayer.
-
-In addition to library modules, ExoPlayer has extension modules that depend on
-external libraries to provide additional functionality. Some extensions are
-available from the Maven repository, whereas others must be built manually.
-Browse the [extensions directory][] and their individual READMEs for details.
