-## Persistent storage
+## Using a Volume for storage
 
-The container file system only lives as long as the container does, so when a container crashes and restarts, changes to the filesystem will be lost and the container will restart from a clean slate. To access more-persistent storage, outside the container file system, you need a [*volume*](/docs/user-guide/volumes). This is especially important to stateful applications, such as key-value stores and databases.
