+Translations of scikit-learn documentation
+------------------------------------------
+
+Translation’s purpose is to ease reading and understanding in languages
+other than English. Its aim is to help people who do not understand English
+or have doubts about its interpretation. Additionally, some people prefer
+to read documentation in their native language, but please bear in mind that
+the only official documentation is the English one [#f1]_.
+
+Those translation efforts are community initiatives and we have no control
+on them.
+If you want to contribute or report an issue with the translation, please
+contact the authors of the translation.
+Some available translations are linked here to improve their dissemination
+and promote community efforts.
