Nice to hear it worked.
I have once created a Tryton cheat sheet on A0 paper format. One half showed the windows and menus, the other all the fields and their icons. Generally speaking the interface is not that difficult but you have to understand how the fields work and where the icons are for. I will see if I can find it in my pile of digital garbage and update it to the newest version.
See docs.tryton.org, in certain places it lacks a deeper level, because of the modularity of Tryton. Modules depend on each other or not which makes it hard to write more general documentation. And sometimes this kind tutorial style documentation is rejected.
Maybe you have seen it already, I have created a set of documents on how to install Tryton. It can definitively be improved, so try it out and let me know what you are missing.
