Extra info to Authentication error block

[P3chk1ns0N]

After creating the SSH key you still can get prompted for username and password while trying to add your commit to the repo.
The reason for this is that when you follow this instruction :
"Go to your GitHub account, open the forked repository, click on the code button and then click the copy to clipboard icon."
The link in your clipboard" is an http address.
But for SSH authetication you need a '[email protected]:' address.
