+# Open Graph Protocol
+
+This is a standard that uses websites to tell external websites how a link preview should look
+
+Works by defining `<meta/>` tags like `<meta property="og:{}" content="{}" />`
+
+## Example
+
+```html
+<html prefix="og: https://ogp.me/ns#">
+    <head>
+        <title>The Rock (1996)</title>
+        <meta property="og:title" content="The Rock" />
+        <meta property="og:type" content="video.movie" />
+        <meta property="og:url" content="https://www.imdb.com/title/tt0117500/" />
+        <meta property="og:image" content="https://ia.media-imdb.com/images/rock.jpg" />
+        ...
+    </head>
+...
+</html>
+```
