+This document explains how to change the default ports that NGINX Ingress Controller is configured to use, as well as how to add additional `listen` settings. For more information, please read the [NGINX Listen documentation](http://nginx.org/en/docs/http/ngx_http_core_module.html#listen).
 
 ## Changing Default Ports
 
 By default, NGINX Ingress Controller listens on ports 80 and 443. These ports can be changed easily, but modifying the `listen` ports for your NGINX Ingress resources will require the editing of .tmpl files.
 
-If you are using `ingress` resource you will need to modify:
-- `nginx-plus-ingress.tmpl` if using NGINX Plus
-- `nginx-ingress.tmpl` if using NGINX OSS
-
 If you are using NGINX Ingress Controller CRDs (virtualServer):
 - `nginx-plus-virtualserver.tmpl` for NGINX Plus
 - `nginx-virtualserver.tmpl` if using NGINX OSS
 
-For this example, we will use the `nginx-virtualserver.tmpl` template to change the port from 80 to 85.
-You can find the [nginx-virtualserver template files in our repository](https://github.com/nginxinc/kubernetes-ingress/tree/main/internal/configs/version2).
