-## Feature Gates
-
-The `featureGates` field is an optional set of optional boolean feature enabler.
-The features in the list are experimental features that are not enabled by default.
+## VNC Token Generation Service
 
-To enable a feature, add its name to the `featureGates` list and set it to true.
-Missing or false feature gates disables the feature.
+The  [VM Console Proxy](https://github.com/kubevirt/vm-console-proxy)
+can be deployed by SSP operator when it is enabled in the `.spec`.
+It is a service that exposes an API for generating VNC access tokens for VMs.
 
-### `deployVmConsoleProxy`
-
-Set the `deployVmConsoleProxy` feature gate to true to allow the operator
-to deploy VM console proxy resources.
-
-Resources will be deployed that provide access to the VNC console of a KubeVirt VM,
-enabling users to access VMs without requiring access to the cluster's API.
