 ##### Cluster Labels
 
-Teleport 5.0 also adds the ability to set labels on Trusted Clusters. The labels are set when creating a trusted cluster invite token. This lets teams use the same RBAC controls used on nodes to approve or deny access to clusters. This can be especially useful for MSPs that connect hundreds of customers' clusters - when combined with Access Workflows, cluster access can easily be delegated.
