@@ -36,6 +36,10 @@ You can make this a super basic controller by just disabling everything.
 - In the `handle_head_rotation` function, there is another block of commented code that says the same thing. Uncomment that too.
 - You should now be able to look around with the joystick. Make sure you add the other controls to the input map. (movement, jumping, crouching, sprinting, etc.)
 
+**Slope/staircase:**   
+Credit to @roberto-urbani23  
+In the character inspector, you can uncheck Stop on Slope and set the max angle to 89 (for some reason, 90 will make the player stuck). Also Snap Length to 1 otherwise your character will not remain attached to stairs if you sprint while going downstairs.
+
 **How to change settings:**  
 Click on the character node and there should be settings in the "Feature Settings" group.
