# Localization files for Keychain Keychain uses .po files to handle localization. More information in the Godot documentation: [Localization using gettext](https://docs.godotengine.org/en/stable/tutorials/i18n/localization_using_gettext.html) Simply add a .po file of the language you want to provide localization for, and Keychain will automatically add it to the TranslationServer when the project runs.
