I am having the hardest time understanding this template system. I downloaded it from GitHub and after copying all relevant files to the site, it throws PHP error on the front end:
PHP Code:
--> PHP Fatal error: Uncaught Error: Undefined constant "ZCA_BUTTON_COLOR" in /site/public_html/includes/templates/bootstrap/css/stylesheet_zca_colors.php:73 
In addition, there is no Admin > Tools > ZCA Bootstrap Colors as the FAQ claims.

Can someone point me to the installation instructions and how to use this template as the download contains no readme, no instructions.

Thanks!
