Sorry, but there is no quick instruction for custom taxonomies pages in our theme. Moreover, it is related to WooCommerce. Since our theme simply adds styles to default Shop page that comes with WooCommerce plugin, not with our theme. Sorry, but it is out of our theme support scope.
Also, the article we sent you from the documentation contains information about custom attributes in WooCommerce, it should help you.
Kind Regards
