Next is add the public key into the GitHub repository, please link to the repository and click Setting tab in the upper right..
Back to the server, if the git repo already exist, we need to update the remote url.
Check current url by:
git remote -v
Set the url to new one:
git remote set-url origin git@giftprocessing.github.com:aad-wsux/giving-day-gift-processing-app.git
Now back to the server, we can use SSH key to access the GitHub, in this case we want to clone repo01 then command will like below.
git clone github-repo01:{UserName}/repo01.git

Your .ssh/config file points to github.com and it doesn't know which key to use when it's time to do the pull.
