+                Defaults to a DVC repository in the current working directory.
+                Both HTTP and SSH protocols are supported for remote Git repos

+                a commit hash or a dvc experiment name.
+                Defaults to the default branch in case of remote repositories.
+                In case of a local repository, if rev is unspecified, it will
+                default to the working directory.
+                If the repo is not a Git repo, this option is ignored.
+            repo (:obj:`Repo`, optional): `Repo` instance.

+                The default is `Repo`.
