You can find a tutorial, everything about editing an article, FAQ an so on at the officialy help:content Page of MediaWiki.
Create a Page
To create a new page, type in a name with underscore separating words after "http://en.openbike.org/wiki/" in the address bar, for example "First_Last", Wiki will automatically create a blank page with the title "First Last", ready for edit.
A more advanced way is the Wiki interlinking method, where the link for a new page is created first on the launch page by typing a new link inside double square brackets. Link to a non-existing page would appear in red, indicating that it's ready to be edited if the user clicks on the link.
Furthermore, it is recommended that your pages are linked together in some logical hierarchy, or at least somewhere in order to be integrated into the Wiki.

Presently this wiki supports four languages technically:
[[pde:Hauptseite]], pde:Hauptseite [[pen:Main_Page]], pen:Main_Page [[pfr:Accueil]], pfr:Accueil [[pnl:Hoofdpagina]], pnl:Hoofdpagina
However, their use has been discouraged after discussion on the mail list, so they don't get linked to presently. Please only use the English language version for the time being.
This is a template for inserting convenient thumbnailed previews:
[[Image:Purge plug.jpg|250px|thumb|left|Purge plugs]]
They can either flow to they left or the right side of the text, size in pixels (px) is optional. It's prudent to ad
at the bottom of sections that contain images, else the layout may flow into the next section below--sometimes this is not wanted.
This is a resized external image with CSS styling and a link--click edit to see how it's done:
Please resize your images before upload. A maximal width of 1024 pixels (or even 800) is mostly enough, image size shouldn't exceed 100 Kilobytes.
