+## MathJax Plugin
+
+If you want to display math equations in your presentation you can easily do so by including this plugin. The plugin is a very thin wrapper around the [MathJax](http://www.mathjax.org/) library. To include it, append the following into the dependencies object to your ```Reveal.initialize()``` call: ```{ src: '../plugin/math/math.js', async: true }```. [Find our more about dependencies](#Dependencies).
+
+The plugin defaults to using [LaTeX](http://en.wikipedia.org/wiki/LaTeX) but that can be adjusted through the ```math``` configuration object. Note that MathJax is loaded from a remote server. If you want to use it offline you'll need to download a copy of the library and adjust the ```mathjax``` configuration value. Here's an example of how the plugin may be configured:
+
+```js
+Reveal.initialize({
+
+       // other options ...
+
+       math: {
+               mathjax: 'http://cdn.mathjax.org/mathjax/latest/MathJax.js',
+
+               // See http://docs.mathjax.org/en/latest/config-files.html
+               config: 'TeX-AMS_HTML-full'
+       }
+
+});
 ```
 
+
 ## Installation
 
 The **basic setup** is for authoring presentations only. The **full setup** gives you access to all reveal.js features as well as the development tasks needed to make changes to the source.
