-## Using the Artifact
+## Using the Artifact: Export
 
 Once the tar artifact has been generated, you will likely want to import, tag,
 and push it to a container repository. Packer can do this for you automatically
 with the [docker-import](/docs/post-processors/docker-import.html) and
 [docker-push](/docs/post-processors/docker-push.html) post-processors.
