If you initialize a directory with git init, how do you add a remote repository?

When you initialize a directory with git init, a new Git repository is created in that directory, but it does not yet have any connection to a remote repository. To establish this connection, you use the command git remote add. This command allows you to specify a name for the remote repository (commonly "origin") and the URL of the remote repository. By adding a remote, you enable your local Git repository to fetch and push changes to the designated remote, facilitating collaboration with others and the synchronization of code.

For instance, the syntax git remote add origin <repository-url> would configure your local repository to track a specific remote repository hosted on platforms such as GitHub, GitLab, or Bitbucket.

In contrast, the other options do not serve the purpose of adding a remote repository. git clone is used to create a clone of an existing repository but is not applicable after initializing a new repository. Options like git link and git new remote are not valid Git commands, which reinforces why git remote add is the correct choice for this operation.
