I think I would make her a notebook.
Get one of those little 89 cent colored notebooks and then organize it by topic/duty, then write as much as the prodecure as you can so she can use it as a quick referral.
Such as:
receptionist
newsletters
claims
etc.
Write a job description, then as many details as you can.
In the back of the book, have a place for troubleshooting that she can refer to.
Don't forget to say where things are kept so she can locate stuff easily.
