+## About
+
+NGINX Ingress Controller is an [Ingress Controller]({{< ref "/nic/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. 
+
+It supports standard [Ingress]({{< ref "/nic/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]({{< ref "/nic/configuration/ingress-resources/advanced-configuration-with-annotations">}}) and the [ConfigMap]({{< ref "/nic/configuration/global-configuration/configmap-resource">}}) resource.
