Add a Bluetooth controller

To add a Bluetooth controller, set your controller in pairing mode.
Then go to the menu by pressing the start button or a keyboard and select Controller Settings.

Select PAIR A BLUETOOTH CONTROLLER:

A list of detected controllers appears, just select yours and the controller is now paired! You can now configure it if it is not already a supported controller!
