79+ # The base image's Dockerfile usually sets this, but it's good practice to be explicit
80+ # to ensure all subsequent commands (if any) and the container's runtime
81+ # operate under this non-privileged user.
82+ USER www-data

84+ # The official dokuwiki/dokuwiki image provides its own ENTRYPOINT.
