+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: with this you can markup textboxes using predefined variables and do whatever customization you want.
+
+Here follows a simple example, see the sections for all the details: 
+
+    mycpu = lain.widgets.cpu({
+        timeout = 4,
+        settings = function()
+            widget:set_markup("Cpu " .. usage)
+        end
+    })
