Create the dedicated branch badges with (extracted from StackOverflow):

git checkout master
git checkout --orphan badges

# Unstage all the files in your working tree.
git rm --cached $(git ls-files)

# Create a dedicated README file, so it's clear what's going on here
echo '# Badges branch' > README.md
git add README.md
git commit -m 'Add dedicated README'
git push origin badges

And then, follow the example.

See a workflow example. Or another more complex example.

Note: You will need to pull auto-generated commits with this technique, or your repo will mess up.
