-### Network Security Groups Support
-Users can use the `IngressClass` resource annotation `oci-native-ingress.oraclecloud.com/network-security-group-ids` to supply
-a comma separated list of Network Security Group OCIDs.
-The supplied NSGs will be associated with the LB associated with the `IngressClass`.
-
-Example:
-```yaml
-apiVersion: networking.k8s.io/v1
-kind: IngressClass
-metadata:
- annotations:
-   oci-native-ingress.oraclecloud.com/network-security-group-ids: ocid1.networksecuritygroup.oc1.abc,ocid1.networksecuritygroup.oc1.xyz
-```
-
-### Load Balancer Preservation on `IngressClass` delete
-If you want the Load Balancer associated with an `IngressClass` resource to be preserved after `IngressClass` is deleted,
-set the annotation `oci-native-ingress.oraclecloud.com/delete-protection-enabled` annotation to `"true"`.
-This annotation defaults to `"false"` when not specified or empty.
-
-OCI Native Ingress Controller will aim to leave the LB in a 'blank' state - clear all NSG associated with the LB,
-delete the Web App Firewall associated with the LB if any, and delete the `default_ingress` BackendSet when the `IngressClass` is deleted with this annotation set to true.
-Please note that users should first delete all `Ingress` resources associated with this `IngressClass` first, or orphaned resources like Listeners, BackendSets, etc. will
-still be present on the LB after the `IngressClass` is deleted
-
-Example:
-```yaml
-apiVersion: networking.k8s.io/v1
-kind: IngressClass
-metadata:
- annotations:
-   oci-native-ingress.oraclecloud.com/delete-protection-enabled: "true"
-```
