 On-disk files in a container are ephemeral, which presents some problems for
-non-trivial applications when running in containers. One problem
-is the loss of files when a container crashes. The kubelet restarts the container
-but with a clean state. A second problem occurs when sharing files
-between containers running together in a `Pod`.
+non-trivial applications when running in containers. One problem occurs when 
+a container crashes or is stopped. Container state is not saved so all of the 
+files that were created or modified during the lifetime of the container are lost. 
+During a crash, kubelet restarts the container with a clean state. 
+Another problem occurs when multiple containers are running in a `Pod` and 
+need to share files. It can be challenging to setup 
+and access a shared filesystem across all of the containers.
 The Kubernetes {{< glossary_tooltip text="volume" term_id="volume" >}} abstraction
 solves both of these problems.
 Familiarity with [Pods](/docs/concepts/workloads/pods/) is suggested.
