+Packaging
+=========
+Before building the package, you must preprocess
+:source-file:`pyproject.toml` to remove parts specific to local
+installations. The easiest way to do this is to run the ``package``
+session using `nox <https://nox.thea.codes/en/stable/>`_:
+
+.. code-block:: console
+
+   $ nox --session package
+
+After running this session, you'll find the ``dist/`` directory
+containing the built distributions. See the ``package`` session in
+:source-file:`noxfile.py` for further details.
+
+You can test the package against all supported versions of Python and
+the core dependencies using the ``testpackage`` nox session.
+
+.. code-block:: console
+
+   $ nox --session testpackage -- dist/*.whl
+
+It takes one positional argument: the package to test. The separator for
+options and arguments, ``--``, is required.
+
+As there are many possible combinations of supported versions, running
+all of these tests will take a long time. You might prefer to run a
+particular combination instead:
+
+.. code-block:: console
+
+   $ nox \
+       --session "testpackage-3.11(numpy='1.26', scipy='1.12')" \
+       -- \
+       dist/*.whl
+
+Use ``nox --list`` to see all supported combinations.
