Getting Mathjax 3.0.1 to work with Gitit

I'm unsure if this is an issue with gitit itself or just a problem with me not knowing how to properly use Mathjax, but I would greatly appreciate help regardless. Gitit by default uses Mathjax 2.7.0, and I would like to modify the configuration file to use Mathjax 3.0.1 (or 3.0.0 would also work). I've tried editing the configuration file to use

`mathjax-script: https://cdn.jsdelivr.net/npm/mathjax@3.0.1/es5/node-main.min.js`

and

`mathjax-script: https://cdnjs.cloudflare.com/ajax/libs/mathjax/3.0.1/es5/startup.js`

but neither of them works, and pages just display the raw text - I suspect I'm just providing the wrong script. Can someone point me in the right direction with getting this to work? Thanks.
