Launching Experience from Printed Documentation

Hello,

Am a new user. I've developed an experience I want to share as a demo. If I want to share the experience with students by having them access the AR via a PDF do I need to include both the QR code AND thingmark on the page? So I would need to include instructions for students to:  (1) download Vuforia View app, (2) click on QR code, (3) when Vuforia View opens, point to "this image" '(thingmark'). I just want to understand if I need to include pictures of both QR code and ThingMark or what easiest process is for the student to view (especially for an audience that is not too tech savvy).

Thank you.
