+## 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
+	},
+	
+	dependencies: [
+		{ src: 'plugin/math/math.js', async: true }
+	]
+
+});
+```
+
+Read MathJax's documentation if you need [HTTPS delivery](http://docs.mathjax.org/en/latest/start.html#secure-access-to-the-cdn) or serving of [specific versions](http://docs.mathjax.org/en/latest/configuration.html#loading-mathjax-from-the-cdn) for stability.
