With `git checkout --to` a new working +tree is associated with the repository. This new working tree is called a +"linked working tree" as opposed to the "main working tree" prepared by "git +init" or "git clone". A repository has one main working tree (if it's not a +bare repository) and zero or more linked working trees. + +Each linked working tree has a private sub-directory in the repository's +$GIT_DIR/worktrees directory.
