Now, if the repository is already existing on a remote machine, and you do not have anything locally, you do git clone instead.
The URL format is simple, it is PROTOCOL:/[user@]remoteMachineAddress/path/to/repository.git
For example, cloning a repository on a machine to which you have SSH access using the "dev" user, residing in /srv/repositories/awesomeproject.git and that machine has the ip 10.11.12.13 you do:
git clone ssh://[email protected]/srv/repositories/awesomeproject.git
