 # Godot Third Person Player Controller
 Yet another third person player controller implementation for Godot.
 
-You can use WASD keys to move around and Space to jump multiple times, and you can also adjust the max number of jumps via an export variable on the Player node.
+I keep adding stuff to this repository, and I make sure that the master branch is stable, and contains the latest features.
