{
    "require": {
        "laravel/framework": "4.*",
        "johntaa/captcha": "dev-master" 
    },
    "minimum-stability": "dev"

Usage

To use the Captcha Service Provider, you must register the provider when bootstrapping your Laravel application. There are essentially two ways to do this.

Find the providers key in app/config/app.php and register the Captcha Service Provider.

    'providers' => array(
        // ...
        'Johntaa\Captcha\CaptchaServiceProvider',
    )

Find the aliases key in app/config/app.php.

    'aliases' => array(
        // ...
        'Captcha' => 'Johntaa\Captcha\Facades\Captcha',
    )

Configuration

To use your own settings, publish config.

$ php artisan config:publish johntaa/captcha
