import { addDecorator } from '@storybook/react';

const StrictModeDecorator = (storyFn) => (
  <StrictMode>
    {storyFn()}
  </StrictMode>
);

const req = require.context('../', true, /\.stories\.js$/);
const loadStories = () => req.keys().forEach(req);

addDecorator(StrictModeDecorator);

Example.stories.js

import React from 'react';
import { storiesOf } from '@storybook/react';
import { withInfo } from '@storybook/addon-info';

const Example = () => (
  <div>Test</div>
)

storiesOf('Example', module)
  .add('With intro description', withInfo(`
    #### Documentation title
  `)(() => (
