I am trying to create a module in prestashop 1.7.* . I have got into a situation which needs me to edit cart.tpl file located in themes/classic/templates/checkout folder. In documentation I came across /themes/[theme_name]/modules which has the description as "Sub-folder for overriding .tpl files and languages files, if necessary." . Unable to find proper explanation I tried creating "MyModule/themes/classic/templates/checkout/cart.tpl" and unfortunately the changes are not reflected in the site. I have no clue what should be done.
P.S When I tried creating a hook and placing it by altering the themes/classic/templates/checkout/cart.tpl file it was successful. I am planning to place my hook in my module's overriding cart.tpl file.
