Preparing for submission of Rift Unity app to 'Concept'

I am also still looking for this guide as well, but I will tell you one odd experience I have had: I downloaded the SteamVR Plugin on the Unity Asset's store because I wanted to investigate Steam as a possibility for publishing my game. I read the instructions that come in the readme file with the plugin and added the Steam script to my in scene camera. Guess what, my game suddenly launched from Oculus Home and when I quit it returned to Oculus home. It even paused. I have no idea why, but you could always download the SteamVR Plugin and read through that code to see if you can use some of that. I have since finished implementing other features of the plugin so now my game launches from Steam and not Oculus Home, but if you only attach the Camera script you may be able to replicate what happened with my game. Best of luck and I am still hoping Oculus will write clearer guidelines as to how to properly code for start, pause and quit.
