As mentioned several times, Github is not your resume. At the very least, it's not mine. Sure, I have a github profile, but the little side projects there don't really have anything to do with my professional work (most recently, data deduplication and video processing).

Also, LaTeX can produce much, much better resumes than markdown. Here's a link to my (extremely dated) resume using the moderncv template: http://jsaxton.com/resume.pdf

It's great for a number of reasons:

1: It immediately gets the attention of the hiring manager, since it looks way better than the typical MS Word resume.

2: It's really easy to edit. If I want to add an item, I just add "/item Did X". It's great.

3: It's plaintext, so you can throw it in git, which is really nice. Since I don't want the public to know if I'm updating my resume, I keep my resume in a private git repository (the same private repo where I keep all my Coursera work).
