Field notes
The documented workflow creates a local certificate authority, adds its root to the macOS trust store, and then emits PEM certificate and key files for a development server. Examples cover localhost, 127.0.0.1, ::1, wildcard names, and bundled multi-name certificates. The page identifies release v1.4.4, lists macOS 10.15 or later, and gives Firefox as an optional case requiring Homebrew's nss package.
