@ -792,7 +792,7 @@ Labels can be used on containers to override default behaviour:
 - `traefik.protocol=https`: override the default `http` protocol
 - `traefik.weight=10`: assign this weight to the container
 - `traefik.enable=false`: disable this container in Træfɪk
- `traefik.frontend.rule=Host`: override the default frontend rule (Default: Host). See [frontends](#frontends).
+- `traefik.frontend.rule=Host:test.traefik.io`: override the default frontend rule (Default: `Host:{containerName}.{domain}`). See [frontends](#frontends).
 - `traefik.frontend.value=test.example.com`: override the default frontend value (Default: `{containerName}.{domain}`) See [frontends](#frontends). Must be associated with label traefik.frontend.rule.
 - `traefik.frontend.passHostHeader=true`: forward client `Host` header to the backend.
 - `traefik.frontend.entryPoints=http,https`: assign this frontend to entry points `http` and `https`. Overrides `defaultEntryPoints`.
