+<Chat client={chatClient} i18nInstance={i18n}>
+  ...
+</Chat>;

+
+If you would like to override certain keys in in-built translation:
+
+```js static
+const i18n = new Streami18n({
+  language: 'nl',
+  translationsForLanguage: {
+    'Nothing yet...': 'Nog Niet ...',
+    '{{ firstUser }} and {{ secondUser }} are typing...':
+      '{{ firstUser }} en {{ secondUser }} zijn aan het typen...',
+  },
+});
+```

+UI will be automatically updated in this case.
