Hey,
maybe you want to change the branch to main so its match the contributing guidelines or edit the contributing gudelines to match the commands under Tips

• ensure that the master branch on your fork is in sync with the original docker-spfx repository

  # assuming you are in the folder of your locally cloned fork....
  git checkout master
  
  # assuming you have a remote named `upstream` pointing to the official **docker-spfx** repo
  git fetch upstream
  
  # update your local main to be a mirror of what's in the main repo
  git pull --rebase upstream master
