 - Create a JSON file for each model, using the model name as the filename. Example: Product.json would update the Product model

+        "_email": "ferris@buellerandco.com", // the criteria/attributes for updateOrCreate are identified with a preleading underscore
+        "department": { // nested values represent relationships and are returned using where($key, $value)->first()
