README

OpenKneeboard is an interactive way to show reference information and take notes in games - especially flight simulators - including in VR.

OpenKneeboard can be controlled via joystick/HOTAS bindings, or a graphics tablet ('artists tablet') such as those made by Wacom or Huion; phones and tablet computers like iPads or Microsoft Surface tablets are not compatible. Mice are not supported in-game.

Go to https://openkneeboard.com for more information.
