-## Configuration Overview
+## Resources
 
-In this setup, the `tailscale-xwiki` service runs the Tailscale daemon to provide secure, private networking. The `xwiki` service is configured to use Tailscale’s network stack via Docker’s `network_mode: service:` syntax. This binds Paperless network interface to the Tailscale container, making the service available only through your Tailscale network (or locally, if needed).
