Train Me Dashboard - Reviews and adaptability?

Hi all, looking at the Train Me download available in the OpenPlace exchange for our org. Am I following correctly that this is ONLY for video uploads? Some of our users do not like videos and prefer a quick reference guide instead. I'd like to layer both options in ....curious if anyone has rolled this out and your thoughts. Also open to any other suggestions for documentation on training and MEC task how-to's.  We have a Teams site but it's clunky at best and would like a one-stop place for all the info. Welcome any insight, thank you!
