+
+How To Use
+
+Put your translation JSON files inside locales directories anywhere under your project or working directory.
+
+Each JSON file must be named as the language code, e.g., en.json, es.json.
+
+Make sure you have a .env file with a locale variable defining your default language code (eg locale=en).
+
+Start the loader
+
+Just import or run this script — it immediately:
+
+Loads all translation files it finds.
+
+Starts a background thread watching those files for any edits.
+
+Set language
+
+Call set_language("fr") to switch the active locale dynamically.
+
+Fetch translations
+
+Use _('some.key') anywhere to get the localized string.
