+      <description>
+        To enable experimental features, add the feature keyword to the list.
+        Whether the feature requires restarting the compositor depends on the
+        given feature. Any experimental feature is not required to still be
+        available, or configurable. Don’t expect adding anything in this
+        setting to be future proof.
+
+        Currently possible keywords:
+
+        • “monitor-config-manager”    — use the new monitor configuration
+                                        system, aimed to replace the old one.
+                                        This enables a higher level configuration
+                                        API to be used by configuration
+                                        applications, as well as the ability to
+                                        configure per logical monitor scale.
+        • “scale-monitor-framebuffer” — makes mutter default to layout logical
+                                        monitors in a logical pixel coordinate
+                                        space, while scaling monitor
+                                        framebuffers instead of window content,
+                                        to manage HiDPI monitors. Does not
+                                        require a restart.
+
+                                        Also enabling “monitor-config-manager”
+                                        is required for this feature to be
