 !> If you return `true`, this will allow the keyboard level code to run, as well.  Returning `false` will override the keyboard level code.  Depending on how the keyboard level function is set up. 
 
+Layer conditions can also be used with the callback function like the following:

 ## Hardware
 
 The A an B lines of the encoders should be wired directly to the MCU, and the C/common lines should be wired to ground.
