+If the `name` input parameter is not provided, all artifacts will be downloaded. To differentiate between downloaded artifacts, a directory denoted by the artifacts name will be created for each individual artifact.
+
+Example, if there are two artfiacts `Artifact-A` and `Artifact-B`, and the directory is `etc/usr/artifacts/`, the directory structure will look like this:
+```
+  etc/usr/artifacts/
+      Artifact-A/
