+		Collision data for KinematicBody2D collisions.
 	</brief_description>
 	<description>
+		Contains collision data for KinematicBody2D collisions. When a [KinematicBody2D] is moved using [method KinematicBody2D.move_and_collide], it stops if it detects a collision with another body. If a collision is detected, a KinematicCollision2D object is returned.
+		This object contains information about the collision, including the colliding object, the remaining motion, and the collision position. This information can be used to calculate a collision response.
