 - Clone or fork the git repo, create a branch
 - Install `pytest` and `nose` on your system: `python -m pip install pytest nose`
-- Modify `nose2pytest/script.py` and `tests/test_script.py`
 - In root folder, run `pytest`
 - Once all tests pass, install tox on your system: on Ubuntu, `python -m pip install tox`
 - Run tox: `tox`
-- Increase the package version in setup.cfg and setup.py
 - Add a python version if latest python is not in `tox.ini`

RELEASING.rst

+Here are the steps on how to make a new release.
+
+1. Create a ``release-VERSION`` branch from ``upstream/master``.
+2. Install ``bumpversion`` and execute:
+
+   ::
+
+    bumpversion minor --new-version 1.0.11
+
+   Changing ``minor`` and ``--new-version`` above accordingly.
+
+3. Push a branch with the changes.
+4. Once all builds pass and at least another maintainer approves, push a tag to ``upstream`` in the format ``v1.0.11`.
+   This will deploy to PyPI.
+5. Merge the PR (do not squash, to keep the tag).
+6. Create a new release on GitHub, posting the contents of the current CHANGELOG.
+7. Open a new PR clearing the ``CHANGELOG.md`` file.
