@ThibodauxRacing Its a little complex. First, plug the controller into the computer. Windows will recognize the controller as a gaming controller. From there you can test the buttons and axes (ie triggers and joysticks) and get an idea of how to map them out. For simplicity, I would recommend this sequence while mapping a controller:
Joystick 1 is what my computer calls my controller. if you double click the area under the primary column, next to the desired input and press or move an input, it will tell the game to use that controller movement for the specific game function.
