+Docs
+====
+
+There's `no good mechanism for publishing documentation
+<https://github.com/pypa/python-packaging-user-guide/pull/266>`_
+easily. If there's a documentation link above, it's probably
+stale because PyPI-based documentation is deprecated. This
+project may have documentation published at ReadTheDocs, but
+probably not. Good luck finding it.
