	### How to update the Furo version
	Update the version in `pyproject.toml`. Always pin to an exact version of Furo.
	However, when updating, closely analyze each commit in the release to check for any changes that would break our fork. We want to make sure that our HTML files are always in sync with Furo. If they have made any changes, then add them back to our copy of the file.

This also improves our project metadata so that our Readme will now be included on the PyPI page.
