+name: Run Containerized Script
+description: |
+  This action provides a way to run commands on a custom image, 
+  while letting Github handle the setup and teardown of the container, as well as any environment variables and mounts. 
+  Useful when you need to run something on a custom image, but do not wish to run the entire workflow with the `container:` directive.
