+
+Storybook for Marko is a UI development environment for your Marko components.
+With it, you can visualize different states of your UI components and develop them interactively.
+
+![Storybook Screenshot](docs/demo.gif)
+
+Storybook runs outside of your app.
+So you can develop UI components in isolation without worrying about app specific dependencies and requirements.
+
+## Getting Started
+
+```sh
+npm i -g @storybook/cli
+cd my-marko-app
+getstorybook
+```
+
+For more information visit: [storybook.js.org](https://storybook.js.org)
+
+* * *
+
+Storybook also comes with a lot of [addons](https://storybook.js.org/addons/introduction) and a great API to customize as you wish.
+You can also build a [static version](https://storybook.js.org/basics/exporting-storybook) of your storybook and deploy it anywhere you want.
+
+Here are some featured storybooks that you can reference to see how Storybook works:
