Once you have the dependencies installed, run the following command:
$> npm install
There are two template files:
index.php.tplsass/colors.scss.tpl
If you want to generate them again, you just have to execute grunt template:blue.
You can compile sass files automatically every time it's changed by executing the following command:
$> grunt watch:blue
$> grunt dist
It generates a .zip file per color scheme: blue (default), red, black and purple. The index.php and colors.scss are generated from the variables in themes.json. The screenshots are taken from screenshot/{color scheme}/screenshot.png.
