Need help introducing new lead mentor to FRC

[frcguy]

Our school just hired a shop teacher who will become our new lead mentor in the fall. He has a mechanical engineering background but no experience with any of the FIRST programs. I'm struggling with how to introduce him and bring him up to speed on all aspects of FRC, from the administrative stuff to all of the technical subjects. I'd like to send him stuff like the various manuals, ask him to create a Chief Delphi account and start looking here, etc. but am afraid he will have trouble understanding it without any context or prior information. Does anyone have advice? I can only communicate with him by email for the next 3 weeks or so. Thanks in advance!
