+### Q: I cannot see a cursor. What should I do?
+
+If no cursor is showing (sometimes reported by people running vwmare), try
+adding `WLR_NO_HARDWARE_CURSORS=1` to `~/.config/labwc/environment`.
+
+If cursors do not update as expected, try installing a cursor theme (for
+example `Adwaita`) and set `XCURSOR_THEME` in `~/.config/labwc/environment`
+accordingly (for example `XCURSOR_THEME=Adwaita`).  `labwc` handles missing
+cursor themes by falling back on builtin old X11 cursors, but some applications
+do not resulting in the wrong or no cursor being set.
