+By default, the `$t` method introduced in the [content access](#content-access) section is expected to return a string. This is why you need to typecast to a different type if you're returning something else, for example:
 
 ```typescript
 this.$t<string[]>('hello');
 
 // Alternative
 this.$t('hello') as string[];
 ```
+
+To get hints for the i18n keys when using `$t`, you can add the following to your `app.ts` file:
+
+```typescript
+declare module '@jovotech/framework/dist/types/I18Next' {
+  interface I18NextResources {
+    // Reference resources here
+    en: typeof en;
+  }
+}
+```
