Backlash Compensation

I would like to implement backlash compensation and looking for guidance on where to start. I have been looking at the Klippy code for moves, but think this would be best in the mcu code. Essentially anytime a direction of a stepper motor is changed, it would first move by the amount of backlash compensation. Can anyone offer me guidance of where in the code should I start?
