Usage guide with KinD

[jcpunk]

Please describe the problem you have
KinD lists Contour as a known working ingress layer (https://kind.sigs.k8s.io/docs/user/ingress/)

But some tweaks are required to get the scheduling in place. Could similar documentation be generated for how to use the Contour Operator with KinD? This would facilitate migrating to the more powerful operator frameworks.
