Perhaps a couple more for your FAQ. :)

What is the procedure for adding a fingerprint to the system?

How does the system know that a text file is a shell script? This is
possibly answered by the previous, but I'm thinking of the case where
the script doesn't have #!/bin/sh or #!/usr/bin/perl or whatever in
it's first line.
