Remotes

The copy that everyone shares.

Naming a remote

A remote is another copy of the repository, usually called origin. git remote -v lists what you are connected to, and git remote add attaches another.

Cloning sets up origin for you automatically.
origin/main is your last known view of the remote branch, not the remote itself.

Tracking branches

git push -u origin feature links your local branch to one on the remote, so later pushes and pulls need no arguments.
