It’s for the Orphans!

I often come across GitHub Pages branches (gh-pages) branches that are simply forks from the master branch of the repository.

This is not ideal.

There are several problems with this strategy:

Please sir may I have some more

git checkout --orphan gh-pages

When it comes time to create a GitHub Page for your project, use the above command. This creates a branch that is completely separate from the history of the rest of the repository. You will need to delete the files by running git rm -rf .

If you want to start a disconnected history that records a set of paths that is totally different from the one of start_point, then you should clear the index and the working tree right after creating the orphan branch by running "git rm -rf ." from the top level of the working tree. Afterwards you will be ready to prepare your new files, repopulating the working tree, by copying them from elsewhere, extracting a tarball, etc.

After you have an empty branch, you’re ready to get started on your Jekyll or HTML site with a clean history and a clear conscience.
