+
+Light & simple powerline theme for Git bash for windows
+
+![ScreenShot](ss.png)
+
+
+## Pre-Requisites
+
+* In order for this theme to render correctly, you will need a
+[Powerline-patched font](https://github.com/powerline/fonts).
+
+
+## Installation:
+
+I recommend the following:
+
+```bash
+cd $HOME
+mkdir -p .bash/themes/git_bash_windows_powerline
+git clone https://github.com/dhwanish-3/git-bash-powerline-theme.git .bash/themes/git_bash_powerline_theme
+```
+
+then add the following to your .bashrc:
+
+```bash
+# Theme
+THEME=$HOME/.bash/themes/git_bash_powerline_theme/theme.bash
+if [ -f $THEME ]; then
+   . $THEME
+fi
+unset THEME
+```
