-# Experimental Feature: ClusterResourceSet (beta)
+# ClusterResourceSet (GA)
 
 The `ClusterResourceSet` feature is introduced to provide a way to automatically apply a set of resources (such as CNI/CSI) defined by users to matching newly-created/existing clusters.
+`ClusterResourceSet` provides a basic solution for installing & managing resources, while for advanced use cases an addon provider must be used.
 
 **Feature gate name**: `ClusterResourceSet`
 
 **Variable name to enable/disable the feature gate**: `EXP_CLUSTER_RESOURCE_SET`
 
-The `ClusterResourceSet` feature is enabled by default, but can be disabled by setting the `EXP_CLUSTER_RESOURCE_SET` environment variable to `false`.
+The `ClusterResourceSet` feature is now GA and is enabled by default, but can be disabled by setting the `EXP_CLUSTER_RESOURCE_SET` environment variable to `false`.
