After you have installed the `anam/captcha`, open the `config/app.php` file which is included with Laravel and add the following lines.

In the `$providers` array add the following service provider.

```
'Anam\Captcha\ServiceProvider\CaptchaServiceProvider'
```

Add the facade of this package to the `$aliases` array.

```
'Captcha' => 'Anam\Captcha\Facade\Captcha'
```

You can now use this facade in place of instantiating the converter yourself in the following examples.

```

Run vendor publish to add the captcha.php file to config:

```
php artisan vendor:publish --tag=CaptchaConfig
