Add package to composer.json

{
    "require": {
        "kris/laravel-form-builder": "1.6.*"
    }
}

run composer update

Then add Service provider to config/app.php

<?php
return [
    // ...

    'providers' => [
        // ...
        'Kris\LaravelFormBuilder\FormBuilderServiceProvider'
    ]
];

And Facade (also in config/app.php)

<?php
return [
    // ...

    'aliases' => [
        // ...
        'FormBuilder' => 'Kris\LaravelFormBuilder\Facades\FormBuilder'
    ]
];

Notice: This package will add illuminate/html package and load Aliases (Form, Html) if they do not exist in the IoC container
