Conclusion

Associate a remote repository

git remote add origin <url>
# Where origin is the default remote repository name, you can also modify it yourself
# The url can be the ssh protocol or the http protocol. It is recommended to use ssh, which is more secure.

Delete a remote repository

git remote rm origin

View a remote repository

git remote -v

Push commit to remote repository

git push origin master

git push -u origin master
# -u parameter is to associate the local master branch with the master branch of the remote repository, which is generally used to push the code to the remote repository for the first time.

Caption

The current situation is that your local repository already exists, but you must have a remote repository so that your code can be developed collaboratively by others, and can also be used as a backup of a local repository.
