 [NGINX Kubernetes Gateway][nginx-kubernetes-gateway] is an open-source project that provides an implementation of the Gateway API using [NGINX][nginx] as the data plane. The goal of this project is to implement the core Gateway API -- Gateway, GatewayClass, HTTPRoute, TCPRoute, TLSRoute, and UDPRoute -- to configure an HTTP or TCP/UDP load balancer, reverse-proxy, or API gateway for applications running on Kubernetes. NGINX Kubernetes Gateway is currently under development and supports a subset of the Gateway API.
 
 If you have any suggestions or experience issues with NGINX Kubernetes Gateway, please [create an issue][nginx-issue-new] or a [discussion][nginx-disc-new] on GitHub. You can also ask for help in the [#nginx-kubernetes-gateway channel on NGINX slack][nginx-slack].
