I've been enjoying using a similar tool called docsify[1], which is a static page that renders markdown files in browser. Basically as self-contained as Markdeep / TeXMe but more flexible.
The link I provided (their documentation page) is the demo page. The source code is at https://github.com/docsifyjs/docsify/tree/master/docs which is a single static index.html that renders a bunch of markdown files.
