+## Authorization
+
+Waterline exposes a dashboard at the `/waterline` URL. By default, you will only be able to access this dashboard in the local environment. However, within your `app/Providers/WaterlineServiceProvider.php` file, there is an authorization gate definition. This authorization gate controls access to Waterline in non-local environments.
+
+## Upgrading Waterline
+
+After upgrading Waterline you must publish the latest assets.
+
+```bash
+composer require laravel-workflow/waterline
+
+php artisan waterline:publish
