How do I output to Oculus Rift on Unity 4.6?

May I know the best and easiest way to have Unity 4.6 running on game mode display on Oculus Rift?

I have installed all the required downloads from https://developer.oculusvr.com/?action=dl&p=sdk&v=21

From the integration guide, it makes it sound like all I have to do is import OculusUnityIntegration.unitypackage and the OculusUnityIntegrationTuscanyDemo.unitypackage. So when I "Press the Play button at the top of the editor. The scene will start with the Rift device controlling the camera's view." But doing so will only show the game where the output does not go to the Oculus Rift, and I can't even control the game view with mouse and keyboard.

I tried changing Oculus display mode but Unity still does not output to the Oculus Rift. I know my Oculus Rift works because executable file demos I have downloaded elsewhere works fine.

I read that you can change output display mode in Unity but I don't see where that option is and my Unity version is up to date. Is there some switch I am missing or script I should add? Please advice
