+### Knative
+
+[Knative][knative] is a serverless platform built on Kubernetes.  Knative Serving provides a simple API for running stateless containers with automatic management of URLs, traffic splitting between revisions, request-based autoscaling (including scale to zero), and automatic TLS provisioning.  Knative Serving supports multiple HTTP routers through a plugin architecture, including a [gateway API plugin][knative-net-gateway-api] which is currently in alpha as not all Knative features are supported.
