Documentation TODO: Get a Markdown parser so that I can more reliably pre-process the codebases's READMEs for static-site gen

[thundergolfer]

At the moment things like images and hrefs don't work properly when moved from repo to the static site sources. To fix this I could do some hacky find/replace work, but it would be better to have a Markdown parser that could make the code more reliable and maintainable.

With a parser I could traverse to each link or image node and update it in-place before re-writing out the result.
