Add some fancy meta tags for sharing etc

A good example of this is how Feather Icons displays custom title, descriotion and even a screenshot when their link is shared on Twitter:

<meta name="description" content="Designed on a 24x24 grid with an emphasis on functionality, consistency and simplicity.">
<meta property="og:title" content="Feather – Simply beautiful open source icons">
<meta property="og:description" content="Designed on a 24x24 grid with an emphasis on functionality, consistency and simplicity.">
<meta property="og:image" content="https://feathericons.com/assets/feather-preview.png">
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@colebemis">
