@@ -73,28 +73,27 @@ You should create a disk in `config/filesystems.php`:
 This package uses [nova-video](https://github.com/mostafaznv/nova-video) to handle videos, so you can choose between [larupload](https://github.com/mostafaznv/larupload) and laravel's built-in  file-system to handle upload process.
 
 1. Create a disk in `config/filesystems.php`:
-```
-'disks' => [
-    'video' => [
-        'driver'     => 'local',
-        'root'       => public_path('uploads/video'),

+            'url'        => env('APP_URL') . 'uploads/video',
+        ]
     ]
-]
-```
-
-> **Note**: If you want to change the disk name, you should rename it in these places: <br>
-> **- With Larupload**: In `App\Models\Video` (disk function of `Attachment` class) <br>
-> **- Without Larupload**: In `App\Nova\Resources\Model` (third argument of make function in `VideoUpload` field) 
-
-
->**Note**: Larupload uses **FFMPEG** to generate cover from original video file, and it will try to find the FFMPEG binary path from your system's environment. but you can define it by yourself by publishing larupload config file. <br> `php artisan vendor:publish --provider="Mostafaznv\Larupload\LaruploadServiceProvider"`

 2. Prepare migration and model:
    1. In the case you chose larupload, there is nothing to do with migration and model. you can find more configuration options in [nova-video](https://github.com/mostafaznv/nova-video) and [larupload](https://github.com/mostafaznv/larupload) documentations.
-   2. But if you chose laravel's file-system, you must make some changes in migration and model. You should remove larupload **trait** and **attachments function** from model and use **string column** instead of **upload column** in migration file.
