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).
