 ```yaml
 labels:
-  traefik.http.routers.hey.rule: Host(`app.hey.com`)
+  traefik.http.routers.hey-web.rule: Host(`app.hey.com`)
 ```
+Traefik rules are in the "service-role-destination" format. The default role will be `web` if no rule is specified. If the destination is not specified, it is not included. To give an example, the above rule would become "traefik.http.routers.hey-web.rule" if it was for the "staging" destination.
 
 Note: The backticks are needed to ensure the rule is passed in correctly and not treated as command substitution by Bash!
