Unless otherwise expressly noted, `function` returns a `wibox.widget.textbox`.
-We say this because, for some widget, `function` return a table to be used for notification and update purposes.
+This is said because, for some widgets, `function` returns a table to be used for notification and update purposes.
+
+Every widget may take either a table or a list of variables as argument.
+
+If it takes a table, you have to define a function variable called `settings` in it, in order to make your customizations.
+
+To markup the textbox, call `widget:set_markup(...)` within `settings`.
+
+You can feed `set_markup` with predefined arguments, see the sections for all the details.
+
+`widget` is a textbox, so you can also threat it like any other `wibox.widget.textbox`.
+
+Here follows an example:
+
+ mycpu = lain.widgets.cpu({
+ timeout = 4,
+ settings = function()
+ widget:set_markup("Cpu " .. usage)
+ end
+ })
