After investigating, I\'ve found mathjax can do this. But when I write some example in my markdown file, it doesn\'t show the correct equations:
I have added this in
One other work-around is to use jupyter notebooks and use the markdown mode in cells to render equations.
Basic stuff seems to work perfectly, like centered equations
\begin{equation}
...
\end{equation}
or inline equations
$ \sum_{\forall i}{x_i^{2}} $
Although, one of the functions that I really wanted did not render at all in github was \mbox{}
, which was a bummer. But, all in all this has been the most successful way of rendering equations on github.
