+Retryable Reads and Writes
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+{+driver-short+} automatically retries certain read and write operations a single time
+if they fail due to a network or server error.
+
+You can explicitly disable retryable reads or retryable writes by setting the ``retryReads`` or
+``retryWrites`` option to ``False`` in the ``MongoClient()`` constructor. The following
+example disables retryable reads and writes for a client:
+
+.. code-block:: python
+
+   client = MongoClient("<connection string>",
+                        retryReads=False, retryWrites=False)
+
+To learn more about supported retryable read operations, see :manual:`Retryable Reads </core/retryable-reads/>`
+in the {+mdb-server+} manual. To learn more about supported retryable write
+operations, see :manual:`Retryable Writes </core/retryable-writes/>` in the {+mdb-server+} manual.
