The whole translation system has been moved to Transifex (learn more about that tool). So if you want to help translating MPC-HC into your native language, first thing you need to do is to sign up at Transifex.
Next thing to do is to visit MPC-HC project page.
On that page you should see the available languages that can be translated:
Check for your native language in that list and request to join the translation team. In case your native language is missing, request its creation.
After you've been approved you can start working. We encourage you to read those tips about common problems you may encounter.
- Please do not download the translation files, modify them and upload again! Always use the online editor available when clicking on the "Translate Now" button.
- Use Transifex's proofreading features.
Enjoy and thanks :-)
