I must say that Nethserver is documentation is really great, much better than most of the open source solutions one can find on the net. I believe that each module should have a help button that provides a link to the full documentation.
The “inline help” page purpose is describing the UI parts in few words, to help on figuring out what each control does, whilst the online doc should help on configuring the system as a whole.
Being inline means
it’s always available, even without Internet connection
it’s (at least should be) bound to the page version it’s describing
Cons:
keeping it up-to-date is quite boring
its translation workflow isn’t based on Transifex, like the UI labels and online manual
My proposal is:
Add a link to inline help page pointing to the online manual
