Git Command on Vundle Install

[Potemkinkuliss]

I use VIM 8.2 on Ubuntu 21.10 and install black via
Plugin 'psf/black'

In the documentation it says

and execute the following in a terminal:
cd ~/.vim/bundle/black
git checkout origin/stable -b stable

This cannot be done since:

fatal: 'origin/stable' is not a commit and a branch 'stable' cannot be created from it

Since black is working I think this can be purged from the documentation.
