-## Caddy Integration
-
-Add a new site block to `/root/caddy/Caddyfile` (adjust the subdomain to your preference):
-
-```caddy
-papers.ahlgrim.bzh {
-    reverse_proxy connected-papers:5000
-}
-```
-
-Then reload Caddy:
-
-```bash
-cd /root/caddy
-docker-compose exec caddy caddy reload --config /etc/caddy/Caddyfile
-```
-
-The container is already attached to the `caddy_mesh` Docker network, so Caddy can reach it by the service name `connected-papers`.
