+### Description
+
+When your Wayland compositor crashes, your entire session dies with it. This
+patch allows your session to survive a restart or crash of dwl by passing in
+the Wayland socket from an outside wrapper program such as
+[wl-restart](https://github.com/Ferdi265/wl-restart).
+
+To use, apply this patch and start dwl with `wl-restart --env dwl [args...]`.
+This automatically restarts dwl when it crashes and tries to keep applications
+alive.
+
+Currently, only **Qt6** supports surviving a compositor restart. The
+environment variable `QT_WAYLAND_RECONNECT=1` needs to be set in order for Qt
+apps to stay alive when the compositor crashes.
