A wiki is pretty free-form, but there if some basic style guidelines are followed by everyone, the site will be easier to maintain by anyone.
So, here are the 'rules' for this wiki.
Page names should be one or two short words. If two words is not clear enough, add a title
At the bottom of the Editing window is an Edit summary field, which turns pink when you start to edit. Enter a couple notes for your editing or click Minor Changes if you are just fixing typos and such
Make a top level header for each page you create
If a page is more than one screen long, make sub-headers and a Table of Contents for the page will automatically be created
Any link that is Red indicates a page that doesn't exist yet
To keep from cluttering up the history, use the Preview button rather than the Save button while editing
