Please, add the equivalent of the English Wikipedia's "Translated page" template at the bottom of the translated articles. It is "required in order to comply with Wikimedia projects' licencing terms (e.g.CC-BY-SA)", so this should be a priority.
Topic on Talk:Content translation
Thanks for your feedback, @V111P
Currently the tool includes information about the translation as part of the edit summary which is enough to comply with the attribution requirements. Having said that, the automatic inclusion of some translation-related templates have been requested before, and the team is considering it for the future (you can check this ticket for more details).
