+Documentation patches
+---------------------
+
+Our documentation is written as `reStructuredText`_ files in the
+:file:`docs` folder, and built using `Sphinx`_.
+
+The preferred language of the documentation is US English. This
+doesn't mean that everyone is expected to pay close attention to
+the different English variants, but it does mean someome might
+suggest a spelling-change, either during review or as a follow-up
+merge-request.
