-There currently is no support for checkboxes, submenus, input boxes
+Menus can contain submenus, by giving an array instead of a function::
+
+  ThemeMenu.set(
+    { "Overlay", {
+       { "Version A", select_overlay_a },
+       { "Version B", select_overlay_b }
+    },
+    { "&Reload overlay", reload_html }

+They can also be checkable, or have checkboxes, by adding a third
+array element containing flags for that::
+
+  ThemeMenu.set(
+    { "Enable overlay",  enable_overlay,  Nageru.CHECKED },    -- Currently checked.
+    { "Enable crashing", make_unstable,   Nageru.CHECKABLE }   -- Can be checked, but isn't currently.
+  )
+
+When such an option is selected, you probably want to rebuild the menu to
+reflect the new state.

+There currently is no support for input boxes, sliders,
 or the likes. However, do note that since the theme is written in unrestricted
 Lua, so you can use e.g. `lua-http <https://github.com/daurnimator/lua-http>`_
 to listen for external connections and accept more complicated inputs
