+This directory holds the translations for the core of Git. This document
+describes how you can contribute to the effort of enhancing the language
+coverage and maintaining the translation.
+
+The localization (l10n) coordinator, Jiang Xin <[email protected]>,
+coordinates our localization effort in his repository:
+
+        https://github.com/gotgit/git-po/
+
+As a contributor for a language XX, you would fork this repository,
+prepare and/or update the translated message file po/XX.po (described
+later), and ask the l10n coordinator to pull your work.
+
+If there are multiple contributors for the same language, please first
+coordinate among yourselves and nominate the team leader for your
+language, so that the l10n coordinator only needs to interact with one
+person per language.
+
+For the list of exiting translations and language teams, see TEAMS file in
+this directory.
