     build translated documents for all languages that exist.
     Invoke ``docstheme-build-translated.sh`` from tox.ini instead of running
     ``sphinx-build`` directly.
+    The following environment variables control the script:
+    ``SKIP_SPHINX_WARNINGS`` to not treat warnings from sphinx-build as an
+    error.
+    ``SPHINX_WARNINGS_TRANS`` will turn on warnings by sphinx-build as
+    an error on translation (use with caution).
