I am trying to find concise, direct instructions on how to create templates (not skins, templates) for MediaWiki and I'm coming up short. While Google has tons of hits, many incorrectly identify skins as templates, and the rest spread the information out through so many other topics that it is simply frustrating. Is there a resource out there that will help me develop MediaWiki page templates in a step-by-step fashion?
I want to start a wiki. Help me decide how best to go about it with long-term planning and goals in mind. [more inside]
