+## PRIVILEGED INTERFACES
+
+Labwc supports a small set of privileged wayland interfaces. All of these
+interfaces are enabled by default for applications unless they are running
+via a sandbox environment supporting the security-context-v1 protocol.
+
+Security conscious users are suggested to use a sandbox framework to run
+potentially untrusted applications as it additionally limits access to the
+filesystem (including labwc configuration) and other services like dbus.
+
+In addition to that, privileged protocols can be restricted for non-sandboxed
+clients by defining a `<privilegedInterfaces>` block:
+
+```
+<privilegedInterfaces>
+  <allow>zwlr_layer_shell_v1</allow>
+  <allow>zwlr_virtual_pointer_manager_v1</allow>
+</privilegedInterfaces>
+```
+
+*<privilegedInterfaces><allow>*
+	Name of the interface that should be allowed.
+
+This is the full list of interfaces that can be controlled with this mechanism:
+
+- `wp_drm_lease_device_v1`
+- `zwlr_gamma_control_manager_v1`
+- `zwlr_output_manager_v1`
