+## Experimental features
+
+Features marked as experimental are optionally made available to users to test and provide feedback.
+
+If you test any experimental feaures, you can give feedback via the feature's tracking issue regarding:
+* Your experience with the feature
+* Issues or problems
+* Suggested improvements
+
+Experimental features are incomplete in design and implementation. Backwards incompatible
+changes may be introduced at any time or support dropped entirely. Therefore experimental 
+features are **not recommended** for use in production environments.
