Set up a GitHub repository with SSH and GPG

This is a beginner's tutorial where we will install Git, create a GitHub repository, generate required keys and connect to GitHub with SSH, clone the repository and sign our commits using GPG.
A proper setup for anyone who wants to work with Git and GitHub in a secure way.

Thanks man, this worked for me. For some reason the other tutorials that only used SSH keys kept erroring for me when I tried to commit things, the GPG part fixed it.

"We got an error doing that"... Everything was identical
