+DESCRIPTION:
+    This sample demonstrates how to convert models returned from a recognize operation
+    to and from a dictionary. The dictionary in this sample is then converted to a
+    JSON file, then the same dictionary is converted back to its original model.
+
+USAGE:
+    python sample_convert_to_and_from_dict_async.py
+
+    Set the environment variables with your own values before running the sample:
+    1) AZURE_FORM_RECOGNIZER_ENDPOINT - the endpoint to your Cognitive Services resource.
+    2) AZURE_FORM_RECOGNIZER_KEY - your Form Recognizer API key
