Git cloning bare repository

git_clone_bare_repository.txt

git clone --mirror: to clone every references (commits, tags, branches)
git push --mirror: to push everything
That would give:

git clone --mirror https://bitbucket.org/exampleuser/repository-to-mirror.git
# Make a bare mirrored clone of the repository

cd repository-to-mirror.git
git remote set-url --push origin https://github.com/exampleuser/mirrored
# Set the push location to your mirror

git push --mirror
