+		High Level Multiplayer API.
 	</brief_description>
 	<description>
+		This class implements most of the logic behind the high level multiplayer API.
+		By default, [SceneTree] has a reference to this class that is used to provide multiplayer capabilities (i.e. RPC/RSET) across the whole scene.
+		It is possible to override the MultiplayerAPI instance used by specific Nodes by setting the [member Node.custom_multiplayer] property, effectively allowing to run both client and server in the same scene.
