Extend markdown plugin to enable MathJax support.

[Piyush3dB]

The extending-markdown-syntax-with-plugins section describes how one can extend the markdown loader to parse, say, MathJax.

I quote part of the section...

If you want to do this you will need to use a custom markdown loader. You can copy the one provided in the default starter here. Add the relevant packages to your dependencies, including the markdown-it plugins that you want to use and enable them with md.use(require('markdown-it-plugin-name')) within the markdown loader file.

But the link pointed to by 'here' i.e.

https://github.com/gatsbyjs/gatsby-starter-default/blob/master/loaders/markdown-loader/index.js

is broken.

Which is the best example I can follow to extend markdown plugins so that I can enable MathJax support?

I have looked at issue #134 which seems to be a hack and not currently the recommended way of doing it. Also, I'd like to be able to just follow the instructions on the README page to achieve this. I'm a C++ dev and this JS stack is very foreign to me so any guidance would be very much appreciated!

Hey so sorry! The old default starter got moved recently to one named "kitchen sink" and I forgot
to update that link. https ://github.com/gatsbyjs/gatsby-starter-kitchen-sink/blob/master/loaders/markdown-loader/index.js

Could you edit that link in the markdown to point to the new location.

Awesome thanks! I have a partially working solution at gatsbyjs/gatsby-starter-kitchen-sink#1. I'm intending to get this fixed and submit it to the kitchen sink demo.
