I understand what they meant, but it's broad/vague, and not specific/actionable.
We do have a tutorials section in the docs, and we have the https://caddyserver.com/docs/caddyfile/patterns page which are that.
Our question is how are those lacking? Just saying "more please" doesn't help because we don't know what the need is. We can't imagine every single possible usecase, because it's actually infinite. Caddy is a "general purpose webserver" which means "it can do just about anything".
Help us by telling us what specifically what usecase is important to you. We don't have telemetry, we need users to tell us.
