Nice to see this getting some publicity. The markdown-resume-js project that this uses is based on my own markdown resume project at https://github.com/there4/markdown-resume.
It's a project that generates both html and pdf versions of a resume written in markdown. It's distributed as a phar file so you can keep a copy in your bin folder and just keep your resume.md in it's own repo.
This was originally a way to experiment with css descendant selectors and learning more about the capabilities of wkhtmltopdf. It's limited compared to LaTex, but it's reasonable for a simple resume.
