+### Add links to front-end pages
+
+To display a link next to the slug that links to the actual page in the front-end you must pass a function that generates the URL to `NovaPageManager::pagePreviewUrl()`.
+
+As shown in this example:
+
+```php
+use \OptimistDigital\NovaPageManager\NovaPageManager;
+
+NovaPageManager::pagePreviewUrl(function (Page $page) {
+  return env('FRONTEND_URL') . $page->path;
+});
+```
+
 ### Overwrite package resources
 
 You can overwrite the package resources (Page & Region) by setting the config options in `nova-page-manager.php`.
