here is a test example:

$$ \begin{xy} \xymatrix { {\mathscr{C}} & a \ar[r]^f \ar[dr]{g \circ f} & b \ar[d]^g & \ar@{~>}[r]^F & & Fa \ar[r]^{Ff} \ar[dr]*[l]{\scriptstyle F(g\circ f) = Fg\circ Ff} & Fb \ar[d]^{Fg} & {\mathscr{D}} \ && c & \ar@{~>}[r]^F &&& Fc } \end{xy} $$ it should render like http://mhlr.github.io/test.html

`here is a test example: $$ \begin{xy} \xymatrix { {\mathscr{C}} & a \ar[r]^f \ar[dr]{g \circ f} & b \ar[d]^g & \ar@{~>}[r]^F & & Fa \ar[r]^{Ff} \ar[dr]*[l]{\scriptstyle F(g\circ f) = Fg\circ Ff} & Fb \ar[d]^{Fg} & {\mathscr{D}} \ && c & \ar@{~>}[r]^F &&& Fc } \end{xy} $$ it should render like http://mhlr.github.io/test.html`

The easiest way to enable XyJax would be through the MathJax 3rd party repository

## From https://github.com/mathjax/MathJax-third-party-extensions

## Using third party extensions.

We host copy of the third-party extension repository on the MathJax CDN. This means anything you contribute here will be easily available to all MathJax CDN users.

To add the third party repository to your configuration use

or equivalently,

in your configuration. See also the documentation page on third party extensions and this repository.

## From https://github.com/mathjax/MathJax-third-party-extensions/tree/master/xyjax

## Using the MathJax CDN

The MathJax CDN hosts a copy of this single-file version of XyJax via the MathJax third party extension repository. To use the CDN copy, you need MathJax v2.4 (or higher) and configure the third party extension repository as described in the MathJax documentation.

Then add the XyJax extension to your configuration like any other third party extension from the MathJax CDN. For example, your inline configuration might be
