-### Browser Support
+## Browser Support
 
 Slate aims to targeted all of the modern browsers, and eventually the modern mobile platforms. Right now browser support is limited to the latest versions of [Chrome](https://www.google.com/chrome/browser/desktop/), [Firefox](https://www.mozilla.org/en-US/firefox/new/), and [Safari](http://www.apple.com/safari/), but if you are interested in adding support for another modern platform, that is welcomed!
