Hello frendz I have a doubt.... How to add a section below to the footer or at the end of the page, (ie. that may be some text or a link) in prestashop
If you want to edit default footer links you need to read this article Adding or removing links from Prestashop footer
If you want to add your own block in footer you need to use a hook in Prestashop, in your case it's displayFooter and you need to read a Prestashop's developer guide on how to create modules
