 ## List of permissions
 
-We broke down this list into few categories:
+The permissions that are required to run Mizu depend on the configuration.
+By default Mizu requires cluster-wide permissions.
+If these are not available to the user, it is possible to run Mizu in namespace-restricted mode which has a reduced set of requirements.
+This is done by by setting the `mizu-resources-namespace` config option. See [configuration](CONFIGURATION.md) for instructions.
 
-- Required - what is needed for `mizu` to run properly on your k8s cluster
-- Optional - permissions needed for proper name resolving for service & pod IPs
-  - addition required for policy validation
-
-### Required permissions
-
-Mizu needs following permissions on your Kubernetes cluster to run properly

-#### Permissions for Policy rules validation feature (opt)

-  verbs:
-  - get
-  - create

-
-#### Namespace-Restricted mode
-
-Alternatively, in order to restrict Mizu to one namespace only (by setting `agent.namespace` in the config file), Mizu needs the following permissions in that namespace:
-
-```yaml
