 The presence of ``.pyi`` files does not affect the Python interpreter at runtime
 in any way. However, static type checkers will only look at the ``.pyi`` file and
 ignore the corresponding ``.py`` file.

 Users are then able to install the stubs-only package separately to provide
 types for the original library.
 
-Inclusion in sdist
-^^^^^^^^^^^^^^^^^^

-Note that to ensure inclusion of ``.pyi`` and ``py.typed`` files in an sdist
-(.tar.gz archive), you may also need to modify the inclusion rules in your
-``MANIFEST.in`` (see the
-`packaging guide <https://packaging.python.org/en/latest/guides/using-manifest-in/>`__
-for more details on ``MANIFEST.in``). For example:
-
-.. code-block:: text
-
-   global-include *.pyi
-   global-include py.typed
