Work In Progress about help/contribute stuff

I can see so far 3 pages concerning it:

Help:Contents which talks about What is Userbase, some guidelines, and some guide to contribute.
UserBase which talks about What is Userbase
UserBase/Guidelines which is actually more a "Code of conduct": license problem, be nice with other, mixed with some advices to contribute

Rename link to Help:Contents as "Contribute" in the side-bar, and focus on this page on the step-by-step contribute starting guide.
Clean UserBase so that it talks only about what is Userbase, and link it through a "What is Userbase" or "Help" link in the sidebar.
Clean the Guidelines so that it talks about the code of conduct, move everything related to contribute howto on the Contribute (Help:Contents) page.

This section looks perfect to me already

I would shorten it and redirect to the "Contribute" (formerly Help:Contents) page.
