Electronic library and qr code, how to make it easier?

Question

QR codes

Hi all! What is the best way to approach the issue of creating a site, the essence of which is to let the user download a certain kind of literature using a qr code? That is, a person scans the code with a phone, a site opens where you can download it and a brief description of it. You don't need to be able to read online. Not much material, 300 books. Where is it better to fill in and how to fill in books, is it possible to CMS? Traffic is not big people.
