Super good initiative, congrats.
Please, in addition to what Rick99 has said, remember that there are new tools available. Per example the TV site which began a glossary pertinent to many new users. In addition to the glossary being built, the Kaltura record and play back tool allows you to "teach" how to do things.
Per example, see the List of external wiki references to name just this one.
Again congrats on this work your doing and if you need further help about the way the doc pages are structured, please let us know
