+Some Linux distributions offer Anubis [as a native package](https://repology.org/project/anubis-anti-crawler/versions). If you want to install Anubis from your distribution's package manager, consult any upstream documentation for how to install the package. It will either be named `anubis`, `www-apps/anubis` or `www/anubis`.
+
+If you use a systemd-flavoured distribution, then follow the setup instructions for Debian or Red Hat Linux.
