+# Chris Morrell's Fish Theme
+
+This is a theme I designed for myself but have given to a few friends and decided to publish for others' enjoyment.
+
+![Chris Morrell's Fish Theme](https://cloud.githubusercontent.com/assets/21592/4770904/8a58e026-5b89-11e4-927c-42a387b41df0.gif)
+
+## Features
+
+- Minimal base prompt
+- Shows compact git status w/ the number of changed files & current branch
+- Gives a visual indication when you're logged in via SSH, or logged in as anyone
+    but the default user (set the `$default_user` variable to define your default user)
+- Shows indicator if previous command failed
+- Shows a bright red "!" if you're logged in as root
+
+(Note: _This theme is designed for a light-on-dark theme like [Solarized](http://ethanschoonover.com/solarized) but should work in a dark-on-light terminal with a few terminal color tweaks_)
