+## bobthefish
+
+bobthefish is a Powerline-style, Git-aware fish theme optimized for awesome.
+
+![bobthefish][screenshot]
+
+You will probably need a [Powerline-patched font][patching] for this to work.
+[I recommend picking one of these][fonts].
+
+This theme is based loosely on [agnoster][agnoster].
+
+
+### Features
+
+ * A helpful, but not too distracting, greeting.
+ * A subtle timestamp hanging out off to the right.
+ * Powerline-style visual hotness.
+ * More colors than you know what to do with.
+ * An abbreviated path which doesn't abbreviate the name of the current project.
+ * All the things you need to know about Git in a glance.
+ * Visual indication that you can't write to the current directory.
+
+
+### The Prompt
+
+ * Flags:
+ * Previous command failed (!)
+ * Background jobs (%)
+ * You currently have superpowers ($)
+ * User@Host (unless you're the default user)
+ * Abbreviated parent directory
+ * Current directory or Git project name
+ * Current project's Git branch (⭠ master) or detached head (➦ d0dfd9b)
+ * Git status, via colors and flags:
+ * Dirty working directory (*)
+ * Untracked files (…)
+ * Staged changes (~)
+ * Stashed changes ($)
+ * Unpulled commits (-)
+ * Unpushed commits (+)
+ * Unpulled *and* unpushed commits (±)
+ * Abbreviated project-relative path
