+Logging
+~~~~~~~~~~~~
+``redshift_connector`` uses logging for providing detailed error messages regarding IdP authentication. A do-nothing handler is enabled by default as to prevent logs from being output to ``sys.stderr``.
+
+Enable logging in your application to view logs output by ``redshift_connector`` as described in
+the `documentation for Python logging module <https://docs.python.org/3/library/logging.html#/>`_.
