  +## Wayland
  +
  +Wayland support is available, but not everything works as expected. Many people
  +have found a better experience using XWayland which can be achieved launching
  +Alacritty with the `WAYLAND_DISPLAY` environment variable cleared:
  +
  +```sh
  +env WAYLAND_DISPLAY= alacritty
  +```

  +If you're interested in seeing our Wayland support improve, please head over to
  +the [Wayland meta issue] on the _winit_ project to see how you may contribute.
