+## 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.
