+General usage
+-------------
+
 Every widget is output by a `function`.
 
-Unless otherwise expressly noted, `function` returns a `wibox.widget.textbox`.
+For some widgets, `function` returns a `wibox.widget.textbox`, for others 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.
 
-We say this because, for some widget, `function` return a table to be used for notification and update purposes.
+`widget` is a textbox, so you can threat it like any other `wibox.widget.textbox`.
 
-Almost all widgets can be set by an input function called `settings`: you can markup textboxes and do whatever customization within it. 
+Here follows an example: 
+
+    mycpu = lain.widgets.cpu({
+        timeout = 4,
+        settings = function()
+            widget:set_markup("Cpu " .. cpu_now.usage)
+        end
+    })
