#### Configuring `marked`
We use [marked](https://github.com/chjj/marked) to parse Markdown. To customise marked's rendering, you can pass in options when [configuring Reveal](#configuration):
```javascript
Reveal.initialize({
// Options which are passed into marked
// See https://github.com/chjj/marked#options-1
markdown: {
smartypants: true
}
});
