People all over the world use MuseScore, thanks to a vibrant community of translators. If you want to help with an existing translation, or start a new one, see the instructions below. Please ask any questions on the forums, or developers mailing list and share initial work - particularly to avoid further workload, should changes be required.
Handbook and website
If you are interested in translating the website, or the software manual, then introduce yourself on the translation forum. We will then give you access to edit and create new pages for your language. Also see the extensive Translation instructions.
The MuseScore community uses a translation server, making it simpler to collaboratively localize MuseScore. If you want to start translating to a language that is not yet listed, leave a request on the Translation forum so the language can be added.
