+# agnoster's Theme - https://gist.github.com/3712874
+# A Powerline-inspired theme for ZSH
+#
+# # README
+#
+# In order for this theme to render correctly, you will need a
+# [Powerline-patched font](https://gist.github.com/1595572).
+#
+# In addition, I recommend the
+# [Solarized theme](https://github.com/altercation/solarized/) and, if you're
+# using it on Mac OS X, [iTerm 2](http://www.iterm2.com/) over Terminal.app -
+# it has significantly better color fidelity.
+#
+# # Goals
+#
+# The aim of this theme is to only show you *relevant* information. Like most
+# prompts, it will only show git information when in a git working directory.
+# However, it goes a step further: everything from the current user and
+# hostname to whether the last call exited with an error to whether background
+# jobs are running in this shell will all be displayed automatically when
+# appropriate.
