The application uses standard gettext for UI translation. To add a new language:

1. Add the language code to po/LINGUAS
2. Create or update the .po file in the po/ directory
3. Translate the strings using your preferred translation tool

Important for translators: Apart from translating the UI strings, you also need to create localized content:

1. Lesson Content: Create a new lesson file in data/lessons/[language_code].json based on the existing us.json or es.json files. This includes:

   • Lesson titles and descriptions
   • Step instructions and practice text
   • Introduction messages

2. Keyboard Layout: Create a keyboard layout file in data/keyboard_layouts/[language_code].json that matches your language's keyboard layout. This defines:

   • Key positions and labels
   • Finger mapping for proper touch typing guidance

The application automatically detects the system language and loads the appropriate lesson content and keyboard layout. If your language files don't exist, it falls back to the US English versions.
