How do you implement this extension?

[muppsy007]

Hi there. Looks like a pretty new extension. Just wondering how it's used? It looks like a DataObject so I have added it as a $has_one.

private static $has_one = array(
     'Video' => YoutubeEmbed::class
);

But then I take it you have to add it to getCMSFields()? But I can see a field type in the package. Is this more for a has_many relationship where you have a gridfield?
