There's a huge community https://www.linuxserver.io/ for people building "home server" containers that all use the s6-overlay, hundreds of examples there. They have a lot of tutorials and a very busy Discord, Reddit, etc with all levels of experience from container developers to people who don't program and are just getting into Docker. I run a bunch of these containers myself and am pretty happy with how adaptable they are.
