 ### *Controller Support*:
-As of v0.2.0 this mod has basic controller support. Despite this, i still recommend using a keyboard for the best experience as nearly all the controller buttons are pre mapped to native functions leading to conflicts. I am working on improving this for a later release.
+This mod supports controller input with the use of a modifier button, which by default is the Left Bumper. To change the button binding, See the ‘Mod Settings’ section of the .ini file.
+Keep in mind that whilst holding the modifier button, only some basic driving functions are enabled.
