+ ## MathJax
+ 
+ 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 use it you'll need to include it as a reveal.js dependency, [find our more about dependencies here](#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. 
+ 
+ Below is an example of how the plugin can be configured. If you don't intend to change these values you do not need to include the ```math``` config object at all.
+ 
+ ```js
+ Reveal.initialize({
+ 
+       // other options ...
+ 
+       math: {
+               mathjax: 'http://cdn.mathjax.org/mathjax/latest/MathJax.js',
+               config: 'TeX-AMS_HTML-full'  // See http://docs.mathjax.org/en/latest/config-files.html
+       },
        
-       // Optional libraries used to extend on reveal.js
-       { src: 'plugin/leap/leap.js', async: true }
+       dependencies: [
+               { src: 'plugin/math/math.js', async: true }
+       ]
+ 
+ });
  ```
  
+ Read MathJax's documentation if you want [secure delivery](http://docs.mathjax.org/en/latest/start.html#secure-access-to-the-cdn) or serve [specific versons](http://docs.mathjax.org/en/latest/configuration.html#loading-mathjax-from-the-cdn) for stabilty.
