GPG-Keys tutorial

[gangstertoppen]

During the Git introduction I failed to see any instructions on how to link a gpg key to my commits and github account.
Surely setting up a GPG-Key to automatically verify that your commits are made by you is good practice.

I did google it, but as it usually does presented tons of resources and i found myself confused on what resource to use, and i ended up not getting any of them to work without any hiccups.

Would it be possible to consider adding such a tutorial to the git introduction?
