It should really be noted what the commands to enter text, save and quit are.

To begin editing in vi - type "a" (no quotes on any command)

When editing complete hit "esc"

To save file type ":w"

To exit vi type ":q"

I struggled with this for quite some time, and it may be a simple thing for gurus who use vi, but there many people with limited knowledge here (like me) so it may make sense to include the commands in with the actual tutorial.

Thanks for a great howto!
