An UMSL-specific faculty support page can be found here, which features a number of helpful guides that simplify the process of integrating the various technologies into your Canvas course. There are also several useful videos, as well as PDF instruction manuals on incorporating things like MindTap or CourseMate.
There's also a more general video describing how Cengage can be integrated into learning management systems like Canvas, which can be found at this link.
