GIT-CLONE(1)      Git Manual      GIT-CLONE(1)

NAME
  git-clone - Clone a repository into a new directory

SYNOPSIS
  git clone [--template=]
     [-l] [-s] [--no-hardlinks] [-q] [-n] [--bare] [--mirror]
     [-o ] [-b ] [-u ] [--reference ]
     [--depth ] [--recursive] [--]  []
  --bare
   Make a bare GIT repository. That is, instead of creating  and placing the administrative files
   in /.git, make the  itself the $GIT_DIR. This obviously implies the -n because there
   is nowhere to check out the working tree. Also the branch heads at the remote are copied directly to
   corresponding local branch heads, without mapping them to refs/remotes/origin/. When this option is used,
   neither remote-tracking branches nor the related configuration variables are created.

git push --mirror
--mirror
   Instead of naming each ref to push, specifies that all refs under refs/ (which includes but is not limited
   to refs/heads/, refs/remotes/, and refs/tags/) be mirrored to the remote repository. Newly created local
   refs will be pushed to the remote end, locally updated refs will be force updated on the remote end, and
   deleted refs will be removed from the remote end. This is the default if the configuration option
   remote..mirror is set.
