 In this example, we will pass a `--model` option to set the model to be used by our DataTable.
 
 ```
-php artisan datatables:make PostsDataTable --model=Post
+php artisan datatables:make Posts --model
 ```
 
+This will generate a `App\DataTables\PostsDataTable` class that uses `App\Post` as the base model for our query. 
+The exported filename will also be set to `posts_(timestamp)`.
