-If you're deploying traefik as a service within rancher, you can alternatively set these labels on the service to let it only fetch data of its current environment. The settings `endpoint`, `accesskey` and `secretkey` can be omitted then.
+As traefik needs access to the rancher API, you need to set the `endpoint`, `accesskey` and `secretkey` parameters. 
 
-- `io.rancher.container.create_agent=true`
+To enable traefik to fetch information about the Environment it's deployed in only, you need to create an `Environment API Key`. This can be found within the API Key advanced options.
-- `io.rancher.container.agent.role=environment`
 
 Labels can be used on task containers to override default behaviour:
