+### Custom Base URL
+
+To set the base URL for a magic link, you can use the `baseUrl` method. This method ensures that the provided base URL has a trailing slash, making it ready for URL generation.
+
+```php
+$magiclink = MagicLink::create($action);
+
+$magiclink->baseUrl("http://example.com");
+
+$urlShowView = $magiclink->url; // http://example.com/magiclink/...
+```
