+### Add code block syntax highlighting
+
+Using the [`draft-js-prism-plugin`](https://github.com/withspectrum/draft-js-prism-plugin) you can easily add syntax highlighting support to your code blocks!
+
+```JS
+// Install prismjs and draft-js-prism-plugin
+import Prism from 'prismjs';
+import createPrismPlugin from 'draft-js-prism-plugin';
+
+class Editor extends Component {
+  state = {
+    plugins: [
+      // Add the Prism plugin to the plugins array 
+      createPrismPlugin({
+        prism: Prism
+      }),
+      createMarkdownPlugin()
+    ]
+  }
+}

 ## Why fork the `markdown-shortcuts-plugin`?
 
 Writing is a core part of our app, and while the `markdown-shortcuts-plugin` is awesome and battle-tested there are a few opinionated things we wanted to do differently. Rather than bother [@ngs](https://github.com/ngs) with tons of PRs, we figured it'd be better to own that core part of our experience fully.
