I'd be a bit more up-front about what this is about. The users are students, and I'd explain the point of the settings here for notebooks that are used for homework and assignments. This feels a bit abstract and sounds like it could apply to any other use case too, but it should be as specific to teaching. I think the previous paragraph sets this up already, we're not building this product specifically for educators, so there are special considerations here.
I'd make some step-by-step guides here for how to set things up for homework (and maybe some other use cases). 1. create notebook, 2. set permissions this way, 3. ask students to fork, 4. tell students to share with you so you can view, etc.
Or, since you seem to have done some of this already, link to the relevant bits in the other notebooks :) The generic editing document isn't super helpful for educators IMHO.
