 ### History
 
+I discovered the ['agnoster' OMZ theme](https://gist.github.com/agnoster/3712874)
+while looking around for a new OMZ theme. I loved the Powerline styling, but the
+terminal status lines themselves were missing a lot of the information I liked
+having.
+
 This theme was first announced [on my blog](http://bhilburn.org/powerlevel9k-oh-my-zsh-theme/) in December of 2014. At
 the time, the theme was missing some of the more advanced Git information. [Tom Upton](http://www.thomasupton.com/) then [helped me](http://bhilburn.org/powerlevel9k-improved-git-repo-information/) get things
 fixed up with [his `vcs_info` hooks](https://github.com/tupton/dotfiles/blob/master/zsh/zshrc).
