+This is a port of Oh My Zsh's ['Bira'](https://github.com/ohmyzsh/ohmyzsh/blob/master/themes/bira.zsh-theme) theme. It looks the same as the original, except for the following changes:
+
+- Exit code of last command is not shown
+- More informative git prompt (if you want to keep it minimal, please read: https://github.com/Bash-it/bash-it#git-prompt)
+- Position and colour of virtualenv prompt
+- No ruby version prompt
