Help:Editing
CMAQwiki is a MediaWiki, which is the same software that powers Wikipedia (et al). Accordingly, you will often find Wikipedia's editing help useful, though more so (e.g.) regarding the syntax and semantics of editing Wiki markup (which is virtually the same on both MediaWiki instances) than (e.g.) regarding editorial policies (since Wikipedia is far more elaborate in this regard than is CMAQwiki).
