 ## roles
 
-You can define node roles in the Embedded Cluster Config. Roles are particularly useful for multi-node clusters. One or more roles can be selected and assigned to a node when it is joined to the cluster. Node roles can be used to determine which nodes run the Kubernetes control plane, and to assign application workloads to particular nodes.

 :::note
 Roles are not updated or changed after a node is added. If you need to change a node’s role, reset the node and add it again.
