+# 2A Role-Based Access Control
+
+2A leverages the Kubernetes RBAC system and provides a set of standard `ClusterRoles` with
+associated permissions. All `ClusterRoles` are created as part of the HMC helm chart.
+2A roles are based on labels and aggregated permissions, meaning they automatically collect
+rules from other `ClusterRoles` with specific labels.
+
+The following table outlines the roles available in 2A, along with their respective read/write or read-only
+permissions:
+
+| Roles                            | Global Admin | Global Viewer | Namespace Admin | Namespace Editor | Namespace Viewer |
