1. Core Concepts

How Godot Localization Works

1. Wrap all user-facing strings in tr() — Godot's translation function
2. Create translation files (CSV or PO) mapping keys to translated strings
3. Import translation files as Translation resources
4. Switch locale at runtime via TranslationServer.set_locale()

All Control nodes with text, tooltip_text, or placeholder_text properties auto-translate when the value matches a translation key.
