Simpler tutorial for Opengraph and Twitter Cards

[vidluther]

First, thanks for writing this package. I'm new to Laravel and am having trouble understanding how to implement OG and Twitter cards as easily as you have the basic meta tags.

It's not clear to me how I can set a default set of OG and Twitter Card data, and how to render it or modify it.

I can see that meta_tags.php has the option of automatically including certain packages, and apparently I'm supposed to create packages in \App\Providers\MetaTagServiceProvider.php where I have

 $og = new OpenGraphPackage('OG');
        $og->setType('website')
            ->setSiteName('My Sitename')
            ->setTitle('I am a OG title');

And in config/meta_tags.php it says

'packages' => [
        'OG'
        // 'jquery', 'bootstrap', ...
    ],

When I view the pages, it doesn't have anything for open graph .. but if I modify the controller

$og = new OpenGraphPackage('og');
$og->setType('website')
->setSiteName('My Sitename')
->setTitle('My Site Title')
->setUrl(env('APP_URL'));

    Meta::registerPackage($og);

Then when I view the page, I can see the OG data in the source.

My question is, what's the best way to set some defaults for the OG data, and then be able to change it when necessary? I've looked at issue #38 but, it's not clicking in my head..
