+				After initializing the interface you want to use you then need to enable the AR/VR mode of a viewport and rendering should commence.
+				Note that you must enable the AR/VR mode on the main viewport for any device that uses the main output of Godot such as for mobile VR.
 				If you do this for a platform that handles its own output (such as OpenVR) Godot will show just one eye without distortion on screen. Alternatively you can add a separate viewport node to your scene and enable AR/VR on that viewport and it will be used to output to the HMD leaving you free to do anything you like in the main window such as using a separate camera as a spectator camera or render out something completely different.
 				While currently not used you can activate additional interfaces, you may wish to do this if you want to track controllers from other platforms. However at this point in time only one interface can render to an HMD.
