Support Docs missing

Hi – just wanted to try out this great-looking plugin, but when I try and download the docs (http://static.wcjcs.com/docs/wordpress/plugins/?plugin=reverberation) I find that the site is down/page is gone. Is there any other way once could grab these docs? Tough to try and figure out the shortcode 🙂
Thanks!
