+DESCRIPTION:
+    This sample demonstrates how to extract general document information from a document
+    given through a file.
+
+    Note that selection marks returned from begin_analyze_document() do not return the text associated with
+    the checkbox. For the API to return this information, build a custom model to analyze the checkbox and its text.
+    See sample_build_model_async.py for more information.
+
+USAGE:
+    python sample_analyze_document_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
