Addon Development

Helo!

I am creating my first hook, I developed func.php with the function to obtain customer address data based on the zip code, however I am confused as to where to add the .tpl file to present the field where the customer entered the zip code in the front-end, I followed the step-by-step in the advanced hooks development guide, but there I am informed the path var / themes_repository / basic / templates / addons / / hooks for the customer area template hooks, however there is no "basic" folder in the cs.cart directory.

Attached is the file with the directory where, according to the guide, it was to be located in the basic folder
