-ChatCops includes 8 built-in locales with full UI string translations.
+The widget's own text ships in English. For another language, pass your translations in `strings`. Built-in translations for more languages are tracked in [#55](https://github.com/codercops/chatcops/issues/55).
 
 ## Setting a Locale
 
+The widget sends `locale` with every message, and the server asks the model to reply in that language.

+There's no script tag attribute for `strings`, so the widget's buttons and placeholders stay in English here. Use `ChatCops.init` to translate them.

-The widget sends its current `locale` with each request, and the server uses it to select the appropriate strings.
+Error messages the visitor sees come from the widget's `strings` (`errorGeneric`, `errorNetwork`, `errorRateLimit`). The server config also has an `i18n` option, but nothing reads it yet.
