+## Grouping functionality
+
+The Yamaha MusicCast integration implements the grouping services. There are some limitations in the MusicCast system for grouping:
+
+- It is not possible to let mediaplayer entities of the same device (e.g., different zones) be in distinct groups.
+- If a non-main zone is the master of a group, it is not possible to let other mediaplayers of the same device join this group.
