 then you can start two ExternalDNS providers one with `--annotation-filter=kubernetes.io/ingress.class in (nginx-internal)`
 and one with `--annotation-filter=kubernetes.io/ingress.class in (nginx-external)`.
 
+If you need to search for multiple values of said annotation, you can provide a comma separated list, like so:
+`--annotation-filter=kubernetes.io/ingress.class in (nginx-internal, alb-ingress-internal)`.

 Beware when using multiple sources, e.g. `--source=service --source=ingress`, `--annotation-filter` will filter every given source objects.
 If you need to filter only one specific source you have to run a separated external dns service containing only the wanted `--source`  and `--annotation-filter`.
