 A ClusterTemplate is a collection of parameters to describe how a cluster can be constructed. Some parameters are relevant to the infrastructure of the cluster, while others are for the particular COE. In a typical workflow, a user would create a ClusterTemplate, then create one or more clusters using the ClusterTemplate. A ClusterTemplate cannot be updated or deleted if a cluster using this ClusterTemplate still exists.
 
+!!! note "Information about the Default Public ClusterTemplate"
+
+    A default ClusterTemplate, named default-cluster-template, can be created in the environment and used by anyone to deploy new Kubernetes clusters. To use this template, pass the --cluster-template default-cluster-template parameter during cluster creation.

 ### Create a ClusterTemplate
 
 Create a Kubernetes cluster template using the `magnum-fedora-coreos-40` image with the following configuration: `m1.large` flavor for both master and nodes, `public` as the external network, `8.8.8.8` for the DNS nameserver, `calico` for the network driver, and `cinder` for the volume driver. Below is the example command to create the clustertemplate. For more detailed information about the parameters and labels used in the ClusterTemplate, please refer to the [ClusterTemplate](https://docs.openstack.org/magnum/latest/user/index.html#clustertemplate).

     You may need to provide custom values to configure your openstack services, for a simple single region or lab deployment you can supply an additional overrides flag using the example found at `base-helm-configs/aio-example-openstack-overrides.yaml`.
     In other cases such as a multi-region deployment you may want to view the [Multi-Region Support](multi-region-support.md) guide to for a workflow solution.
