 1. The ingress is now available at this address and will route incoming requests to the proper service based on the DNS
    name in the request. To support this, a wildcard DNS A record should be created for the desired domain name. For example,
-   if your Knative base domain is `example.com` then you need to create an A record with domain `*.example.com`
-   pointing the ip address of the ingress.
+   if your Knative base domain is `knative.info` then you need to create an A record or CNAME record with domain `*.knative.info`
+   pointing the ip address or hostname of the ingress.
