Add social meta data to homepage

Hi guys,

I need to add some social meta data to the head of my homepage (only the homepage).

<meta property=”og:title” content=”The title of the page”>
<meta property=”og:description” content=”A longer than the title but still brief description of the content. No html allowed!”>
<meta property=”og:image” content=”Absolute URL to a preview image that is meant to be used and shown everywhere “>
<meta property=”og:site_name” content=”A short name of the source, like domain or name of the magazine / company”>

On the other pages/post that´s automatically generated from the Yoast SEO plugin but not for the homepage. So I loke to add that manually and static. Do you have any reccomendations how to do that? Is there a simple plugin, or should I add the header.php to my child theme and add it there? Other?

Cheers
Michael
