 A runner scale set is a group of homogeneous runners that can be assigned jobs from {% data variables.product.prodname_actions %}. The number of active runners owned by a runner scale set can be controlled by auto-scaling runner solutions such as {% data variables.product.prodname_actions_runner_controller %} (ARC).
 
-You can use runner groups to manage runner scale sets. Similar to self-hosted runners, you can add runner scale sets to existing runner groups. However, runner scale sets can belong to only one runner group at a time and can only have one label assigned to them.
+You can use runner groups to manage runner scale sets. Similar to self-hosted runners, you can add runner scale sets to existing runner groups. However, runner scale sets can belong to only one runner group at a time. A runner scale set can have more than one label, and workflows can target it by its name or by its labels in `runs-on`. Support for multiple labels was added in Actions Runner Controller 0.14.0.
 
 To assign jobs to a runner scale set, you must configure your workflow to reference the runner scale set’s name. For more information, see [AUTOTITLE](/actions/how-tos/manage-runners/use-actions-runner-controller/use-arc-in-a-workflow).
