Can we get a link on the docs page with a little blurb about apisix and how to set it up or use th examples. Just like the other traffic routers found here https://argoproj.github.io/argo-rollouts/features/traffic-management/

Also the examples that you have in getting-started could also go into the examples folder https://github.com/argoproj/argo-rollouts/tree/master/examples
