 ### Keystone Settings
 
+You can configure the use of keystone for authentication in the `spec.auth.keystone` section of the CRD:
+
+```yaml
+spec:
+  [...]
+  auth:
+    keystone:
+      acceptedRoles:
+        - admin
+        - member
+        - service
+      implicitTenants: "swift"
+      revocationInterval: 1200
+      serviceUserSecretName: usersecret
+      tokenCacheSize: 1000
+      url: https://keystone.example-namespace.svc/
+  protocols:
+    swift:
+      accountInUrl: true
+     urlPrefix: /swift
+  [...]
+```
+
 The `keystone`-section allows to configure the Keystone instance to use.
 
 * `acceptedRoles`: The OpenStack Keystone [roles](https://docs.openstack.org/keystone/latest/admin/cli-manage-projects-users-and-roles.html#roles-and-role-assignments) accepted by RGW when authenticating against Keystone.
