### How to render a webcomponent in Storybook with React

The following error is the most common when using Atomico in Storybook with React.

```bash
localhost/:1 Uncaught DOMException: Failed to execute 'define' on 'CustomElementRegistry': this constructor has already been used with this registry
```

We recommend using [@atomico/react](https://atomico.gitbook.io/doc/packages/atomico-react), this package creates a friendly wrapper for React.
