Dute network primer?

Is anyone willing to post primer of Dude subnetted network that we can load and see in Dude (not bitmap)?
I find it pretty confusing, and cannot get how to do some basic things, so I would like to see working example.

It may be easier to post questions about what you don’t understand, as what your post looks like is a request to have someone allow access to a “live” network so you can see what is going on. Most people (read as all) who manage networks would view this as a security issue and would not be willing to do it.
