Is kubenet supported or not?

[bitsofinfo]

Last I looked at the docs here: https://docs.microsoft.com/en-us/azure/application-gateway/ingress-controller-install-existing

it states under pre-reqs: that azure CNI is required....

yet I see on this site, that kubenet is supported?

Where should I be looking for install instructions?
