 # NGINX Kubernetes Gateway
 
-NGINX Kubernetes Gateway is an open source project that provides an implementation of the Kubernetes [Gateway API](https://gateway-api.sigs.k8s.io/) using NGINX as the data plane. 
-The goal of this project is to implement the core Gateway APIs -- `Gateway`, `GatewayClass`, `HTTPRoute`, `TCPRoute`, `TLSRoute` and `UDPRoute` -- in order to configure an HTTP Load Balancer for applications running on Kubernetes.
-NGINX Kubernetes Gateway is currently under development and supports a subset of the Gateway API.

NGINX Kubernetes Gateway is currently under development and supports a subset of the Gateway API.
