+Internationalization (i18n)
+---------------------------
+
+Select2 supports multiple languages by simply including the right
+language JS file (`select2_locale_it.js`, `select2_locale_nl.js` etc.).
+
+Missing a language? Just copy `select2_locale_en.js.template`, translate
+it and make a pull request back to Select2 here on Github.
