I have written short overviews of each component and I will start writing up the API specification presently. My coding skills are beginner/intermediate, but I'm pretty good at dreaming up schemes, so I am going to focus on putting together a really nice documentation set.
This way, when it comes to coding it, it's all more or less laid out for me, and ideally, others who will be helping build it. I will be writing the protocol buffer specifications as soon as I have the documents done for all of the protocols, which should only be a day or a few.
https://www.gitbook.com is the site I am using to do this, and there is a nice WYSIWYG editor, which you can use on the network or with a locally installed app. I had been spoiled when @faddat showed me Quip - realtime collaborative WYSIWYG document editing. This is not collaborative, but it's better than steemit.com's editor, shall we say :)
