How to set up a remote Git repository on Qt Creator?

Question

git

Every time it gives this, although I added a remote repository.

fatal: 'PGMeditor' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

or when I think I've added it:

git push
fatal: No configured push destination.
Either specify the URL from the command-line or configure a remote repository using

    git remote add <name> <url>

and then push using the remote name

    git push <name>
