# Config ## Translations - UI strings must use translation keys (never hard-coded) - Source translations in `**/config/locales/en.yml` can be modified directly - Other translations managed via Crowdin ```bash bundle exec i18n-tasks missing # Show missing translation keys bundle exec i18n-tasks unused # Show unused translation keys bundle exec i18n-tasks normalize # Fix/normalize translation files bundle exec i18n-tasks check-consistent-interpolations # Check interpolation consistency ```
