 # Multi Test: Test helpers for multi-contract interactions
 
+Warning: **Alpha Software** Designed for internal use only.
+
+This is used for testing cosmwasm-plus contracts, we have no API
+stability currently. We are working on refactoring it and will
+expose a more refined version for use in other contracts. (Ideally
+in cosmwasm-plus 0.9 or 0.10).
+
+**Use at your own risk**
+
 Let us run unit tests with contracts calling contracts, and calling
 in and out of bank.
 
 This only works with contracts and bank currently. We are working
 on refactoring to make it more extensible for more handlers,
 including custom messages/queries as well as IBC.
