+# Git Branch in Prompt
+
+Working with Git and it's great branching/merging features is amazing. Constantly switching branches can be confusing though as you have to run `git status` to see which branch you're currently on.
+
+The solution to this is to have your terminal prompt display the current branch. There's a [number][1] [of][3] [articles][3] [available][4] online about how to achieve this.
+
+I based this project mainly on [Aaron Crane's solution][1].

+
+
+## Installation
+
+Clone the project to a `.bash` folder in your home directory:
+
+    git clone git://github.com/jimeh/git-branch-in-prompt.git ~/.bash
+
+Edit your `~/.bash_profile` or `~/.profile` and add the following to the top:
+
+    export DOTBASH=~/.bash
+    source $DOTBASH/main.sh
+    PS1="\u@\h:\w\[$txtcyn\]\$git_branch\[$txtrst\]\\$ "
+
+Configure your prompt by editing the `PS1 variable`. For a list of available colors check `colors.sh`.
