+## Development Testing
+
+This repo includes a test workflow - _.github/workflows/test-actions.yml_ - that is configured to run on each commit to the `develop` (and `main`) branch.  This workflow runs the latest code as a test, saving the updated sample files as artifacts, should the output need to be checked.
