+"""This script reads the testbed file, generates reimbursement IDs,
+and saves the updated testbed with the new IDs.
+
+It should be run from the `fieldExtraction` directory, with the testbed file co-located in the same directory.
+The output will be saved as `Doczy-Testbed-with-Reimb-IDs.xlsx`.
+
+Run it with `poetry run python -m src.testbed.add_reimb_id_to_testbed`
