 # Building
 Run `./build.sh` or if you are running Arch Linux, then you can find it on aur under the name vr-video-player-git (`yay -S vr-video-player-git`).\
 Dependencies needed when building using `build.sh`: `glm, glew, sdl2, openvr, libx11, libxcomposite, libxfixes, libmpv`.
 
 # How to use
-vr-video-player has two options. Either capture a window and view it in vr or a work-in-progress built-in mpv option.
