 ### Alternatives
 
-* [WP multisite + Caddy](https://skippy.net/caddy-docker-php-wordpress): arguments against using the Wordpress Docker image, keeps the whole wp install outside the image, and instead focuses on properly configuring PHP-FPM. Has the advantage of being reusable for other PHP projects. Is well argumented.
