<meta name=”twitter:card” content=”summary” />
<meta name=”twitter:site” content=”@yoursite” />
<meta name=”twitter:title” content=”Your Title” />
<meta name=”twitter:description” content=”Your description.” />
<meta name=”twitter:image” content=”https://where-your-image-is-hosted/name.jpg” />See: https://developer.twitter.com/en/docs/tweets/optimize-with-cards/guides/getting-started.html
