 		Animation Player that uses a node graph for the blending.
 	</brief_description>
 	<description>
-		Animation Player that uses a node graph for the blending. This kind of player is very useful when animating character or other skeleton based rigs, because it can combine several animations to form a desired pose.
+		A node graph tool for blending multiple animations bound to an [AnimationPlayer]. Especially useful for animating characters or other skeleton-based rigs. It can combine several animations to form a desired pose.
