 ## Developing
 
 Committing to this repository requires [signing your commits](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) (`git config commit.gpgsign true`) unless you are making edits via the GitHub.com text editor interface. As of August 2022 the preferred signing method is [SSH commit signatures](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification#ssh-commit-signature-verification), but GPG signing is also acceptable. You should add your signing key to your GitHub profile.
