 The `naughty.layout.box` allows to provide custom widgets to use within the
 notifications.
 
+The `awful.wallpaper` provides a non-intereactive "backgroud" for one or more
+`screen`. While it uses normal widget, it will not automatically be repainted
+if they change. It will also not provide any mouse events.

 Finally, the `awful.titlebar`, while not technically a real `wibox`, acts
 exactly the same way and allows to attach widgets on each side of clients.

+The AwesomeWM wallpaper module, `awful.wallpaper` support both per-screen wallpaper
+and wallpaper across multiple screens. In the default configuration, `request::wallpaper`
+is emitted everytime a screen is added, moved, resized or when the bars
+(`awful.wibar`) are moved.
+
+This is will suited for single-screen wallpaper. If you wish to use multi-screen wallpaper,
+it is better to create a global wallpaper object and edit it when the screen change.
