+### About managed NGINX Ingress deployments
+
+NGINX Ingress is deployed into the `gitlab-managed-apps` namespace, using the [official Helm chart](https://github.com/kubernetes/charts/tree/master/stable/nginx-ingress). NGINX Ingress will be [externally reachable via the Load Balancer's IP](https://docs.gitlab.com/ce/user/project/clusters/index.html#getting-the-external-ip-address).
+
+NGINX is configured for Prometheus monitoring, by setting:
+* `enable-vts-status: "true"`, to export Prometheus metrics
+* `prometheus.io/scrape: "true"`, to enable automatic discovery
+* `prometheus.io/port: "10254"`, to specify the metrics port
+
+When used in conjunction with the GitLab deployed Prometheus service, response metrics will be automatically collected.

 ### Manually setting up NGINX Ingress for Prometheus monitoring
 Version 0.9.0 and above of [NGINX ingress](https://github.com/kubernetes/ingress/tree/master/controllers/nginx) have built-in support for exporting Prometheus metrics. To enable, a ConfigMap setting must be passed: `enable-vts-status: "true"`. Once enabled, a Prometheus metrics endpoint will start running on port 10254.
