Hi Michael I am happy to add some documentation.
I forked the repo but am having trouble with the markdown. The code examples are not rendering correctly. I am on a mac and using https://itunes.apple.com/us/app/marked-2/id890031187?mt=12 I use a emacs or some other text editor to change the md. What tools do you use for editing viewing spark markdown files?
