+OculusVR integration
+--------------------
+
+OculusVR support is currently experimental, and only DX11 is tested. To build
+with OculusVR HDM support enabled you must set `OVR_DIR` enviroment variable:
+
+	set OVR_DIR=<path to OculusSDK>
+
+And generate project files with `--with-ovr` option:
+
+	genie --with-ovr vs2012
+
+In `LibOVR/Include` create trampoline headers `OVR_D3D.h` and `OVR_GL.h`.
+
+`OVR_D3D.h` should contain:
+
+	#include "../Src/OVR_CAPI_D3D.h"
+
+`OVR_GL.h` should contain:
+
+	#include "../Src/OVR_CAPI_GL.h"
