-    Usage of ``setup.cfg`` is not recommended unless for very simple use cases. ``.cfg``
-    files use a different parser than ``pytest.ini`` and ``tox.ini`` which might cause hard to track
-    down problems.
-    When possible, it is recommended to use the latter files, or ``pyproject.toml``, to hold your
-    pytest configuration.
+``setup.cfg`` file usage for pytest has been deprecated, its recommended to use ``tox.ini`` or ``pyproject.toml``
