In order to be able to commit changes to the repo, you must
clone it using an ‘ssh://’ URL.
Cloning the repo with
ssh is similar to cloning
with the Git protocol or with HTTP, but the URL is different:
$ git clone ssh://firstname.lastname@example.org/srv/git/gawk.git -| ...
Here, you should replace ‘yourname’ in the command with the user name you chose for use on Savannah.
