== Frequently Asked Questions ==

= The code is just being displayed raw. It isn't being converted into a code box or anything. What's wrong? =

Make sure your theme's `footer.php` file has `` somewhere inside of it, otherwise the plugin won't be able to do it's thing.

= Highlighting doesn't work and my browser hangs, why?

Try excluding this plugin's Javascript from any performance optimizations your site may be doing that involve minifying or concatenating JS.
