It's possible to write your slides using Markdown. To enable Markdown simply add the ```data-markdown``` attribute to your ```<section>``` elements and reveal.js will automatically load the JavaScript parser.
This is based on [data-markdown](https://gist.github.com/1343518) from [Paul Irish](https://github.com/paulirish) which in turn uses [showdown](https://github.com/coreyti/showdown/). Syntax support seems limited judging by my initial tests, this may be due to conflicts with the reveal.js styles. Updates to come.

This is sensitive to indentation (avoid mixing tabs and spaces) and line breaks (avoid consecutive breaks). Updates to come.
