     1  ## Overview
     2  Contour is an Ingress controller for Kubernetes that works by deploying the [Envoy proxy][1] as a reverse proxy and load balancer.
     3  Contour supports dynamic configuration updates out of the box while maintaining a lightweight profile.
     4  
     5  Contour also introduces a new ingress API [HTTPProxy][2] which is implemented via a Custom Resource Definition (CRD).
     6  Its goal is to expand upon the functionality of the Ingress API to allow for a richer user experience as well as solve shortcomings in the original design.
     7  
     8  ## Prerequisites
     9  Contour is tested with Kubernetes clusters running version [1.15 and later][4], but should work with earlier versions where Custom Resource Definitions are supported (Kubernetes 1.7+).
    10  
    11  RBAC must be enabled on your cluster.
