pull** IMAGE, before it starts the container from that image.
+Several files will be automatically created within the container when it is run.
+These include `/etc/hosts`, `/etc/hostname`, and `/etc/resolv.conf` to manage
+networking. These will be based on the host's version of the files, though they
+can be customized with options (for example, **--dns** will override the host's
+DNS servers in the created `resolv.conf`). Additionally, an empty file is
+created in each container to indicate to programs they are running in a
+container. This file is located at `/run/.containerenv`.
