 ## Configure infrastructure-related settings
 
-You can configure deployment and service settings for all data plane instances by editing the `NginxProxy` resource at the GatewayClass level. These settings can also be specified under `nginx.` in the Helm values file. 
-
-Users can specify these settings for NGINX data plane deployments:
-
-- _replicas_ specifies the number of data plane pod replicas..
-- The `pod` section provides control over pod scheduling and lifecycle behavior. You can configure settings such as _terminationGracePeriodSeconds_, _tolerations_, _nodeSelector_, _affinity_, and _topologySpreadConstraints_. Use _extraVolumes_ to mount additional volumes, typically alongside container-level _extraVolumeMounts_.
-- The `container` defines settings for the NGINX container itself., such as resource requests and limits using _resources_, and lifecycle hooks like preStop or postStart via _lifecycle_. You can also specify _extraVolumeMounts_ to mount additional volumes defined at the pod level.
+You can configure deployment and service settings for all data plane instances by editing the `NginxProxy` resource at the Gateway or GatewayClass level. These settings can also be specified under `nginx.` in the Helm values file. You can edit things such as replicas, pod scheduling options, container resource limits, extra volume mounts, service types and load balancer settings. 
 
-Users can specify these settings for NGINX data plane service in the `service` config:
-
-- _type_ specifies the service type for the NGINX data plane. Allowed values are ClusterIP, NodePort, or LoadBalancer.
-- _externalTrafficPolicy_ sets how external traffic is handled. `Local` preserves the client’s source IP.
-- _annotations_ adds custom annotations to the NGINX data plane service.
-
-The below fields can only be specified when the `service.type` is `LoadBalancer`:
-- _loadBalancerIP_ specifies the static IP address of the load balancer.
-- _loadBalancerClass_ specifies the class of the load balancer implementation this service belongs to.
-- _loadBalancerSourceRanges_ specifies IP ranges (CIDR) that are allowed to access the load balancer.
+The following command creates an `NginxProxy` resource with 2 replicas, sets `container.resources.requests` to 100m CPU and 128Mi memory, configures a 90 second `pod.terminationGracePeriodSeconds`, and sets the service type to `LoadBalancer` with IP `192.87.9.1` and AWS NLB annotation.
