Localizing the Mod Launcher
The Mod Launcher only ships with English localization. However, it supports being localized via XML files.
You can start creating your own localization of the Mod Launcher by downloading a template XML file from the sidebar of this page (you will want the newest one available!), placing it in a "Languages" folder next to the Mod Launcher's executable and editing the
Translation nodes inside it.
The language can be selected under the Launcher tab of Launcher Settings.
Any language strings not included in your XML file will fall back to their English defaults.
