+# switcher-progress
+
+This repository contains a workflow for verifying that a translation meets the
+PEP 545 language switcher requirements.
+
+It can be run from the
+[Actions tab](https://github.com/StanFromIreland/switcher-progress/actions/workflows/switcher-requirements-progress.yml)
+by selecting "Run workflow" and specifying the translation's language code (e.g.
+`pl` or `ro`).
