-## About Laravel
+Updates information about courses and chapters
 
-Laravel is a web application framework with expressive, elegant syntax. We believe development must be an enjoyable and creative experience to be truly fulfilling. Laravel takes the pain out of development by easing common tasks used in many web projects, such as:
+```php
+php artisan symfonycast:update
+```
 
-- [Simple, fast routing engine](https://laravel.com/docs/routing).
+Dispatch chapters marked as sync offline to queue for download 
-- [Powerful dependency injection container](https://laravel.com/docs/container).
-- Multiple back-ends for [session](https://laravel.com/docs/session) and [cache](https://laravel.com/docs/cache) storage.
-- Expressive, intuitive [database ORM](https://laravel.com/docs/eloquent).
-- Database agnostic [schema migrations](https://laravel.com/docs/migrations).
-- [Robust background job processing](https://laravel.com/docs/queues).
-- [Real-time event broadcasting](https://laravel.com/docs/broadcasting).
 
-Laravel is accessible, powerful, and provides tools required for large, robust applications.
+```php
+php artisan symfonycast:sync
+```
+Dispatch chapters without file size to  queue for update
 
-## Learning Laravel
+```php
+php artisan symfonycast:video_size
+```
 
-Laravel has the most extensive and thorough [documentation](https://laravel.com/docs) and video tutorial library of all modern web application frameworks, making it a breeze to get started with the framework.
+## Queues 
 
-If you don't feel like reading, [Laracasts](https://laracasts.com) can help. Laracasts contains over 2000 video tutorials on a range of topics including Laravel, modern PHP, unit testing, and JavaScript. Boost your skills by digging into our comprehensive video library.
+Downloading chapters marked as sync offline:
 
-## Laravel Sponsors
+```php
+php artisan queue:work --queue=downloadVideoFile
+```
+Get information about file size of chapters:
