If you’re fluent in a language other than English, and have some spare time, you can help us translate Quod Libet. Translation is a continuous process on an active projects like this - as developers add new features or modify existing text used, new translations will be needed.
Of course, there might be mistakes in the English, too! Please let us know if you find them.
We use Weblate for translations which means you need to:
Create an account on https://hosted.weblate.org
Visit https://hosted.weblate.org/engage/quodlibet and start translating
Any translation changes on Weblate will automatically be merged back into our code base after some time
Similarly any code changes that result in changed or new source strings will periodically be pushed to Weblate so you can start translating them.
Although not recommended, you can also translate without Weblate on your local computer, see How-to (Legacy Manual Process) for more information.
