Creating form classes is easy. With a simple artisan command:

php artisan make:form Forms/SongForm --fields="name:text, lyrics:textarea, publish:checkbox"

Form is created in path app/Forms/SongForm.php with content:

<?php namespace App\Forms;

use Kris\LaravelFormBuilder\Form;

class SongForm extends Form
{
    public function buildForm()
    {
        $this
            ->add('name', 'text')
            ->add('lyrics', 'textarea')
            ->add('publish', 'checkbox');
    }
}

If you want to instantiate empty form withoutl any fields, just skip passing --fields parameter:

    php artisan make:form Forms/PostForm

Gives:

<?php namespace App\Forms;

use Kris\LaravelFormBuilder\Form;

class PostForm extends Form
{
    public function buildForm()
    {
        // Add fields here...
    }
}

After that instantiate the class in the controller and pass it to view:

<?php namespace App/Http/Controllers;

use Illuminate\Routing\Controller as BaseController;
use Kris\LaravelFormBuilder\FormBuilder;

class SongsController extends BaseController {

    public function create(FormBuilder $formBuilder)
    {
        $form = $formBuilder->create('App\Forms\SongForm', [
            'method' => 'POST',
            'url' => route('song.store')
        ]);

        return view('song.create', compact('form'));
    }
}

Print the form in view with form() helper function:

<!-- resources/views/song/create.blade.php -->

@extend('layouts.master')

@section('content')
    {!! form($form) !!}
@endsection

Above code will generate this html:

<form method="POST" action="http://example.dev/songs">
    <input name="_token" type="hidden" value="FaHZmwcnaOeaJzVdyp4Ml8B6l1N1DLUDsZmsjRFL">
    <div class="form-group">
        <label for="name" class="control-label">Name</label>
        <input type="text" class="form-control" id="name">
    </div>
    <div class="form-group">
        <label for="lyrics" class="control-label">Lyrics</label>
        <textarea name="lyrics" class="form-control"></textarea>
    </div>
    <div class="form-group">
        <label for="publish" class="control-label">Publish</label>
        <input type="checkbox" name="publish" id="publish">
    </div>
</form>
