Copy `ServeCommand.php` to `app/Console/Commands/` folder and  edit `app/Console/Kernel.php` and put `ServerCommand`, like this:

```php
<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Laravel\Lumen\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel
{
    protected $commands = [
        Commands\ServeCommand::class,
    ];
```

If you run the command:

```
php artisan serve
```

will start the local server based on `APP_HOST` (from your `.env`)

You can change the host or port:

```
php artisan serve --host 0.0.0.0 --port 8000
```
