+# Godot OpenVR GDNative module
+This module is provided as is, all files are contained within the addons/godot-openvr-asset folder
+
+This module requires **Godot 3.1 or newer** to run, **Godot 3.2** is highly recommended.
+
+The scenes subfolder contains a number of godot scenes that help you set up your project. 
+For basic functionality start with adding ovr_first_person.tcn to your project.
+Also make sure that vsync is turned off in your project settings.
+
+Source code for this module can be found here:
+https://github.com/GodotVR/godot_openvr
+
+Also note that we have a support asset containing a number of useful scenes to get you going building VR applications in Godot:
+https://github.com/GodotVR/godot-vr-common
+
+Documentation on using this asset can be found here:
+https://github.com/GodotVR/godot-openvr-asset/wiki
+
+HDR support
+-----------
+HDR support was added to OpenVR but requires the keep_3d_linear flag added to Godot 3.2. This will ensure rendering inside of the headset is correct. The preview on screen will look darker. You can solve this by using a separate viewport.
+
+When using Godot 3.1 you need to either use the GLES2 renderer or turn HDR off on the viewport used to render to the HMD.
+
+Licensing

+The dynamic libraries supplier by Valve fall under Valve's own license.
