Create SSH Keys
In this class, we recommend using SSH to manage git. On each device you need to use git, please perform the following on each device you wish to use git from:
ssh-keygen # It is safe to accept the defaults here
cat ~/.ssh/id_rsa.pub # Copy this to your clipboard
With this in your clipboard, go to this page: https://github.com/settings/keys
Click "New SSH Key" and paste in your key.
