The above PDF is an older copy of the document still available from the Help menu:
The current in-app version is about 3 pages longer and has (if memory serves) a number of corrections to the previous one.
The Help menu also has the ‘Agents and Dashboards’ PDF which has a links to a companion TBX. It does occur to me that the items in the Help menu point to different resources: a Mac Help filer, 2 x PDF, A link to buy a book and to this forum. I wonder if it might help if these two PDFs were made clearer as such.
If helping a (potential) new user, IME, a key thing is finding a metaphor that makes sense to them. No harm in starting with one that you like but some people like very literal non-tech metaphors, others are happy with tech abstraction.
