+# Experimental features
+
+New features are considered experimental before they are production-ready.
+
+Exposing experimental features gives you an opportunity to try our newest features sooner.
+
+In return, your feedback helps us make sure that our new features are reliable and useful.
+
+## Feedback
+
+We appreciate any and all feedback you want to provide. 
+
+The best place to provide feedback and ask questions is on [Mina Protocol Discord](https://bit.ly/MinaDiscord]. 
+
+Experimental features are in active development and your feedback is especially appreciated.
