## Translations
 
Translation source (`.ts`) files for OpenToonz GUI are located in `toonz/sources/translations`.
If you create new `.ts` files for your language or polish existing ones,
please send us those modifications as pull-requests.
[Qt Linguist](http://doc.qt.io/qt-5.6/linguist-translators.html) is useful for translating them.
 
Please send us Qt message (`.qm`) files with `.ts` files if you can make the following modifications.
