-NGINX Ingress Controller is an [Ingress Controller]({{< relref "glossary.md#ingress-controller">}}) implementation for NGINX and NGINX Plus that can load balance Websocket, gRPC, TCP and UDP applications. It supports standard [Ingress]({{< relref "glossary.md#ingress">}}) features such as content-based routing and TLS/SSL termination. Several NGINX and NGINX Plus features are available as extensions to Ingress resources through [Annotations]({{< relref "configuration/ingress-resources/advanced-configuration-with-annotations">}}) and the [ConfigMap]({{< relref "configuration/global-configuration/configmap-resource">}}) resource.
+NGINX Ingress Controller is an [Ingress Controller]({{< relref "glossary.md#ingress-controller">}}) implementation for [NGINX](https://nginx.org) and [NGINX Plus](https://www.f5.com/products/nginx/nginx-plus) that can load balance Websocket, gRPC, TCP and UDP applications. NGINX Ingress Controller gives you a way to manage NGINX through the [Kubernetes](https://kubernetes.io/) API, and is built to handle the continuous change that happens in Kubernetes environments.

 NGINX Ingress Controller supports the [VirtualServer and VirtualServerRoute resources]({{< relref "configuration/virtualserver-and-virtualserverroute-resources">}}) as alternatives to Ingress, enabling traffic splitting and advanced content-based routing. It also supports TCP, UDP and TLS Passthrough load balancing using [TransportServer resources]({{< relref "configuration/transportserver-resource">}}).
