  ## Wayland
  -Wayland support is available, but not everything works as expected. Many people
  -have found a better experience using XWayland which can be achieved by
  -launching Alacritty with the `WAYLAND_DISPLAY` environment variable cleared:
  +Wayland is used by default on systems that support it. Using XWayland may
  +circumvent Wayland specific issues and can be enabled through:
  ```sh
  -env WAYLAND_DISPLAY="" alacritty
  +env WINIT_UNIX_BACKEND=x11 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.
