Note it's a json file!
<script type="application/ld+json">

"sameAs" : [ "https://twitter.com/flarum",

}

I written it with mobile device so please add the code inside script tag (means excluding script tag as its html) to a notepad file and change its extension to .json and open it with visual studio code just to check once if there are no errors.
