 I based this project mainly on Aaron Crane's [solution][1].
 
 
 ## Overview
 
-If you `cd` to a Git working directory, you will see the current Git branch name displayed in your terminal prompt. When you're not in a Git working directory, your prompt works like normal.

 ## Configuring
 
-If you followed the above installation instructions, you've added the default prompt style already by defining the `PS1` variable. If you don't know how to customize your prompt, I recommend you check [this][5] how-to.

-Basically, to have the current Git branch shown, simply add `$git_branch` to your `PS1` variable, and make sure the variable value is defined with double quotes. A set of color variables have also been set for you to use. For a list of available colors check `colors.sh`.
