+      att_wm implements river-window-management-v1, providing dwm's window
+      management model — tags, a master/stack layout, monocle and tabbed
+      layouts — on top of river 0.4's non-monolithic compositor. Tag and window
+      state is published over a JSON-lines unix socket for bars such as
+      quickshell, and driven back the other way with the att_wmctl CLI.
