     - The `pose_reset_key` can be set to allow resetting the view to the original position and orientation
     - Both of these keys can be set to XInput buttons & combinations or single keyboard/mouse keys as outlined in User Settings - Load Keys
     - The `pitch_radius` can be set to make the pitch emulation move along a semicircle instead of just tilting up/down in place
+- OpenTrack 3DoF support is available over UDP loopback at the default 4242 port when `use_open_track` is true. It can be used in combination with Pitch/Yaw emulation
 
 #### User Presets
 - If you swap between different convergence settings in-game, sometimes you will end up with black bars on the sides of the screen or you may not see a change immediately. If you reload/restart/reinitialize the VR mod, you should see the change
