2 With `add`, if no branch argument, and neither of `-b` nor
3 `-B` nor `--detach` are given, the command defaults to
4 creating a new branch from HEAD. If `worktree.guessRemote` is
5 set to true, `worktree add` tries to find a remote-tracking
6 branch whose name uniquely matches the new branch name. If
7 such a branch exists, it is checked out and set as "upstream"
8 for the new branch. If no such match can be found, it falls
9 back to creating a new branch from the current HEAD.
