Users may not be aware that the filename chosen to add extra
configuration in /etc/nginx/conf.d may interfere with nginx-proxy.
nginx-proxy stores its configuration at /etc/nginx/conf.d/default.conf.
Any files that come before default.conf in alphabetical order will be
applied before default.conf and vice-versa.
This is confusing, because the documentation does not specify how
exactly nginx-proxy interacts with nginx.
This can be remedied by a simple note alerting the users of the
importance of filename choices.
