Do you want mathjax when viewing the readme file? If github is broken it is on their end, they don't have the best coverage of org features.
Or do you want mathjax in the generated html in a github pages? That can be done...
Another place that org doesn't work (at all) is pypi.
Hello,
I am trying to use MathJax with a README.org file on github, but I am
having no luck. I believe that this "just works" with markdown on
github.
The best that I could find was a bug report by karthink [fn:1] that
refers to following instructions on a wiki. But, I can't find that wiki,
nor can I find any other advice that works. DuckDuckGo suggested an AI,
but that seems to be a source of infinitely many wrong guesses and about
as much frustration (it's like trying to get a straight answer out of a
C student).
Any pointers or tips would be appreciated.
TIA,
Leo
