+## Built with and thanks to
 * [nginx](https://nginx.org)
 * [Alpine Linux](https://alpinelinux.org)
 
 ## Tips
-* You can find some [examples](examples) of special backend configurations
-* Don't bind to ports < 1024 (requires root), use NAT/reverse proxy
-* [Permanent Stroage](https://github.com/11notes/alpine-docker-netshare) - Module to store permanent container data via NFS/CIFS and more
+* Only use rootless container runtime (podman, rootless docker)
+* Don't bind to ports < 1024 (requires root), use NAT/reverse proxy (haproxy, traefik, nginx)
