-## RiftQuake
+# Quake for Oculus Rift
 
-[Download Here](https://github.com/swax/Quakespasm-Rift/releases)
+Based on [Quakespasm](http://quakespasm.sourceforge.net/). This enables support for the Oculus Rift for idsoftware's original Quake. You need the Oculus SDK and SDL to compile this.
 
-This is a mod to the rift quakespasm mod by [@phoboslab](https://github.com/phoboslab)

-Improvements:
-* Minimal head movement. The center of the crosshair is always in front of your face. Moving your head looks around relative to the crosshair.
-* More accurate. Only your mouse controls the crosshair. Moving you head does not change your aim.
-* 3D Crosshair. Projected out in 3D space at whatever you're pointing at.
-* Menus and console rendered in the 3D world.
 
-Use ~ to access the console and type 'r_oculusrift 1' to activate the rift view. 
+Use ~ to access the console and type `r_oculusrift 1` to activate the rift view. You may want to disable view bobbing with `cl_bob 0`.
