1. Watched the new Mars Tutorial - Deliver Content that intelligently interacts in the Real World 2. Information is missing ( for novices like me) - The tutorial does not explain how the image/image marker) in the simulation view ( the image of one) was first inserted. In the future, it would be helpful to include video links to other video tutorials needed to view BEFORE using MARS tutorials like this one. If Mars is only for advanced users, please let me know so I can cancel the subscription. Many thanks.
