 ## Further Customization
 
 To make things easier I use LESS to build So Simple Theme's stylesheets. If you want to make some minor cosmetic alterations, take a look at `variables.less` in `assets/less/`. Changing some of the following variables can help make the theme your own. Just compile `main.less` using your preprocessor of choice and off you go -- I like [CodeKit](http://incident57.com/codekit/) for OS X and [Prepros](http://alphapixels.com/prepros/) for Windows.
