Some plugins try to guess the appropriate required values, but it is not always possible. For instance, plugin :ref:`Readthedocs` cannot guess the documentation URL, since it can differ from ``http://<PypiPackageName>.readthedocs.io`` (for instance, the documentation URL of `sphinxcontrib-packages <http://pypi.python.org/pypi/sphinxcontrib-packages>`_ is http://packages.readthedocs.io and not http://spinxcontrib-packages.readthedocs.io). Thus, it may be necessary to provide additional information. This can be done using YAML files.
