+====================
+Packaging guidelines
+====================
+
+Thank you very much for packaging vdirsyncer! The following guidelines should
+help you to avoid some common pitfalls.
+
+While they are called guidelines and therefore theoretically not mandatory, if
+you consider going a different direction, please first open an issue or contact
+me otherwise instead of just going ahead. These guidelines exist for my own
+convenience too.
+
+Obtaining the source code
+=========================
+
+The main distribution channel is `PyPI
+<https://pypi.python.org/pypi/vdirsyncer>`_, and source tarballs can be
+obtained there. Do not use the ones from GitHub: Their tarballs contain useless
+junk and are more of a distraction than anything else.
+
+I give each release a tag in the git repo. If you want to get notified of new
+releases, `GitHub's feed
+<https://github.com/untitaker/vdirsyncer/releases.atom>`_ is a good way.
+
+Dependency versions
+===================
+
+It is strongly discouraged to package vdirsyncer as a Python 2 application.
+Future releases will only work on Python 3.3 and newer versions.
+
+As with most Python packages, ``setup.py`` denotes the runtime dependencies of
+vdirsyncer. It also contains lower-bound versions of each dependency. Older
+versions will be rejected by the testsuite.
+
+Testing
+=======
+
+Everything testing-related goes through the ``Makefile`` in the root of the
+repository or PyPI package. Trying to e.g. run ``py.test`` directly will
+require a lot of environment variables to be set (for configuration) and you
+probably don't want to deal with that.
+
+You can install the testing dependencies with ``make test-install``. You
+probably don't want this since it will use pip to download the dependencies.
+Alternatively you can find the testing dependencies in
+``test-requirements.txt``, again with lower-bound version requirements.
+
+You also have to have vdirsyncer fully installed at this point. Merely
+``cd``-ing into the tarball will not be sufficient.
+
+Running the tests happens with ``make test``.
+
+Documentation
+=============
+
+You can find a list of dependencies in ``docs-requirements.txt``.
+
+Change into the ``docs/`` directory and build whatever format you want. That
+said, I only take care of the HTML docs' formatting -- other targets (such as
+the generated manpage) may look like garbage.
