+Data Manager API utilities and samples for Python
+=================================================
+
+Utilities and code samples for working with the Data Manager API and Python.
+
+Requirements
+------------
+* Python 3.10+
+
+Installation
+------------
+
+.. code-block::
+
+  pip install .
+
+Documentation
+-------------
+Please refer to our `Developer Site`_ for documentation on how to install,
+configure, and use this client library.
+
+Run samples
+-----------
+
+Samples are provided in the `samples/` directory, and the `samples/sampledata`
+directory contains samples of input files you can use with the samples.
+
+To run a sample, invoke the script using the command line. You can pass
+arguments to the script in one of two ways:
+
+1. Explicitly, on the command line
+-----------------------------------
+
+.. code-block:: bash
+
+   python3 -m samples.events.ingest_events \
+     --operating_account_type='GOOGLE_ADS' \
+     --operating_account_id='<operating_account_id>' \
+     --conversion_action_id='<conversion_action_id>' \
+     --json_file='</path/to/your/file>'
+
+2. Using an arguments file
+--------------------------
+
+You can also save arguments in a file, with one argument per line.
+
+.. code-block:: text
+
+   --operating_account_type
+   GOOGLE_ADS
+   --operating_account_id
+   <operating_account_id>
+   --conversion_action_id
+   <conversion_action_id>
+   --json_file
+   </path/to/your/file>
+
+Then, run the sample by passing the file path, prefixed with the ``@``
+character.
+
+.. code-block:: bash
+
+   python3 -m samples.events.ingest_events @/path/to/your/args.txt
