Documentation now in the post. Checkout the wiki.
Good point. Unfortunately, the lack of documentation extends from the lack of implementation. http://ocdoc.cil.li/tutorial:custom_oses should be a good place to start, since that provides the grounds for OS creation, but otherwise, the only real difference from, say Node.js, is the inclusion of the components object, and the computer object. I'll be sure to post a link to better documentation when I get around to making it.
