Adding a remote repository

Using a remote repository, in addition to a local repository, is truly essential when using Git, for two main reasons:

• Being able to back up your code, and avoid losing progress in case of a problem
• Having a "source of truth" in order to be able to collaborate with other people

For these two reasons, it will therefore be necessary to link a remote repository (generally called a "remote repository") and push local changes to that repository.
