 ## In-memory data storage
 
-In-memory data storage is intended for testing only. This storage is volatile and temporary. The data is cleared each time the bot is restarted. To use the in-memory storage for testing purposes, you will need to do two things. First, within the **Conversation.UpdateContainer** method, create a new instance of the in-memory storage:
