 		Kinematic bodies are special types of bodies that are meant to be user-controlled. They are not affected by physics at all (to other types of bodies, such a character or a rigid body, these are the same as a static body). They have however, two main uses:
 		Simulated Motion: When these bodies are moved manually, either from code or from an AnimationPlayer (with process mode set to fixed), the physics will automatically compute an estimate of their linear and angular velocity. This makes them very useful for moving platforms or other AnimationPlayer-controlled objects (like a door, a bridge that opens, etc).
-		Kinematic Characters: KinematicBody2D also has an api for moving objects (the [method move] method) while performing collision tests. This makes them really useful to implement characters that collide against a world, but that don't require advanced physics.

 			<description>
+				Moves the body along a vector. [code]linear_velocity[/code] is a value in pixels per second. If the body collides with another, it will slide along the other body rather than stop immediately. If the floor the node stands on is also a KinematicBody2D, the node will follow the floor's motion. This works regardless of the method used to move the floor. You can use this to make moving or rotating platforms.
+				[code]floor_normal[/code] is the up direction, used to determine what is a wall and what is a floor or a ceiling. If set to the default value of [code]Vector2(0, 0)[/code], everything is considered a wall. This is useful for topdown games.
+				If the body is standing on a slope and the horizontal speed (relative to the floor's speed) goes below [code]slope_stop_min_velocity[/code], the body will stop completely. This prevents the body from sliding down slopes.
+				If the body collides, it will change direction a maximum of [code]max_bounces[/code] times before it stops.
+				[code]floor_max_angle[/code] is the maximum angle (in radians) where a slope is still considered a floor (or a ceiling), rather than a wall.
+				Returns the movement that remained when the body stopped. To get more detailed information about collisions that occured, use [method get_slide_collision].
