 pip 25.1 suggested for development
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 Dependencies for development (build and testing) are now specified as `Dependency Groups
 <https://packaging.python.org/en/latest/specifications/dependency-groups/#dependency-groups>`_
 instead of `individual requirements files
 <https://pip.pypa.io/en/stable/reference/requirements-file-format/>`_.

 Consequently, a version of pip that supports Dependency Groups is suggested, namely
 version 25.1 or higher. Note that if you install build/testing dependencies manually (by
 copying the list from ``pyproject.toml``), then an older version of pip is sufficient.
diff --git a/doc/devel/development_setup.rst b/doc/devel/development_setup.rst

      Install the Python dependencies with ::

        pip install -r requirements/dev/dev-requirements.txt
        pip install -U pip  # You may skip this step if pip 25.1 is already available.
        pip install --group dev

      Remember to activate the environment whenever you start working on Matplotlib!

diff --git a/doc/devel/release_guide.rst b/doc/devel/release_guide.rst
 build the docs from the ``ver-doc`` branch.  An easy way to arrange this is::

  pip install matplotlib
  pip install -r requirements/doc/doc-requirements.txt
  pip install --groupdoc
  git checkout v3.7.0-doc
