+# A Prezto version of Agnoster, a Powerline-inspired theme for Zsh.
+#
+# This theme requires a [patched Powerline
+# font](https://github.com/powerline/fonts). In addition, it looks better with
+# the [Solarized theme](https://github.com/altercation/solarized/).
+#
+# Based in the
+# [original theme](https://github.com/agnoster/agnoster-zsh-theme), in the
+# [Oh My Zsh version of
+# Agnoster](https://github.com/robbyrussell/oh-my-zsh/blob/master/themes/agnoster.zsh-theme),
+# and in the [Powerlevel9k theme](https://github.com/bhilburn/powerlevel9k).
+#
+# Uses the 'editor' and the 'git' Prezto modules.
