+# Localization of Godot Engine documentation
+
+This repository contains the localization templates and catalogs for the
+[official documentation](https://docs.godotengine.org) of the [Godot
+[Engine](https://godotengine.org) project.
+
+The source strings are extracted by sphinx-gettext from the
+[godot-docs](https://github.com/godotengine/godot-docs) repository.
+
+The translations are contributed through [Hosted
+Weblate](https://hosted.weblate.org/projects/godot-engine/godot-docs/) and
+synced manually in this repository.
+
