 # Release images
 
-When you create a cluster on a provider by using the Red Hat Advanced Cluster Management for Kubernetes, you must specify a release image to use for the new cluster.  The release image specifies which version of Red Hat OpenShift Container Platform is used to build the cluster.
+When you create a cluster on a provider by using the Red Hat Advanced Cluster Management for Kubernetes, you must specify a release image to use for the new cluster. The release image specifies which version of Red Hat OpenShift Container Platform is used to build the cluster.
 
 The files that reference the release images are `yaml` files that are maintained in the `acm-hive-openshift-releases` GitHub repository. Red Hat Advanced Cluster Management for Kubernetes uses those files to create the list of the available release images in the console. The repository contains the `clusterImageSets` directory and the `subscription` directory, which are the directories that you use when working with the relase images. 
 
 The `clusterImageSets` directory contains the following directories:
 
-* fast - Contains files that reference the latest two versions of the release images for each OpenShift Container Platform version that is supported
-* releases - Contains files that reference all of the release images for each OpenShift Container Platform version that is supported. **Note:** These releases have not all been tested and determined to be stable.
-* stable - Contains files that reference the latest two stable versions of the release images for each OpenShift Container Platform version that is supported. The release images in this folder are tested and verified

 The `subscription` directory contains files that specify where the list of release images is pulled from. The default release images for Red Hat Advanced Cluster Management are provided in a Quay.io directory. They are referenced by the files in the [acm-hive-openshift-releases GitHub repository](https://github.com/open-cluster-management/acm-hive-openshift-releases).
