=====================================
Related Projects
=====================================

Projects implementing the scikit-learn estimator API are encouraged to use
the `scikit-learn-contrib template <https://github.com/scikit-learn-contrib/project-template>`_
which facilitates best practices for testing and documenting estimators.
The `scikit-learn-contrib GitHub organization <https://github.com/scikit-learn-contrib/scikit-learn-contrib>`_
also accepts high-quality contributions of repositories conforming to this
template.

Below is a list of sister-projects, extensions and domain specific packages.

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]_.

on them.
If you want to contribute or report an issue with the translation, please
contact the authors of the translation.
