go to http://wiki.maemo.org/Smart_control
you well get a message like "There is currently no text in this page, you can search for this page title in other pages or edit this page"
then you click "edit this page" and then you can fill it up with info.

If you need help on how to make headlines,links,dialogs,...etc in the edit page there is a help wiki on the bottom, you may want to read it first.

Good luck
