+    
+    mkdir ~/.bash
+    cd ~/.bash
+    git clone git://github.com/mikesten/git-aware-prompt.git
 
 Edit your  `~/.profile` or `~/.bash_profile` and add the following to the top:
 
-    export DOTBASH=~/.bash
-    source $DOTBASH/main.sh
-    export PS1="\u@\h \w\[$txtcyn\]\$git_branch\[$txtrst\]\$ "
+    export GITAWAREPROMPT=~/.bash/git-aware-prompt
+    source $GITAWAREPROMPT/main.sh
+    export PS1="\u@\h \w\[$txtcyn\]\$git_branch\[$txtylw\]\$git_dirty\[$txtrst\]\$ "
