Assuming you are currently starting ED from the launcher (downloaded from the Frontier store...)
First thing you need to do in the Oculus Home software is go to Settings > General and turn on Unknown Sources.
Then, when you start ED (from the launcher), you should be good to go. In the event that it isn't working in the HMD, go to the ED Graphics settings and expand the 3D section and make sure that one of the HMD options is selected.
At that point, ED should be playing through your Rift (mirrored on your screen).
Prepare to be wowed
