+The process for importing Docker images into a local offline Docker registry depends on
+**your network security policy**. Please consult your IT staff to find an accepted and approved
+process by which external resources can be imported or temporarily accessed. Note that these scanners are [updated periodically](../index.md#maintenance-and-update-of-the-vulnerabilities-database)
+with new definitions, so consider if you're able to make periodic updates yourself.
+
+For details on saving and transporting Docker images as a file, see Docker's documentation on
+[`docker save`](https://docs.docker.com/engine/reference/commandline/save/), [`docker load`](https://docs.docker.com/engine/reference/commandline/load/),
+[`docker export`](https://docs.docker.com/engine/reference/commandline/export/), and [`docker import`](https://docs.docker.com/engine/reference/commandline/import/).
