+# This workflow uses actions that are not certified by GitHub.

+# documentation.

+# This workflow checks out code, builds an image, performs a container image
+# vulnerability scan with Anchore's Grype tool, and integrates the results with GitHub Advanced Security
+# code scanning feature.  For more information on the Anchore scan action usage
+# and parameters, see https://github.com/anchore/scan-action. For more
