      <h1>Welcome to STORYBOOK</h1>
      <p>
        This is a UI component dev environment for your app.
      </p>
      <p>
        We've added some basic stories inside the
        <br />
        <code :style="code">src/stories</code>
        <br />
        directory.
        <br />
        A story is a single state of one or more UI components. You can have as many stories as
        you want.
        <br />
        (Basically a story is like a visual test case.)
      </p>
      <p>
        See these sample
        <br />
        <a :style="link" @click="onClick" role="button" tabIndex="0">stories</a>
        <br />
        for a component called
        <br />
        <code :style="code">Button</code>
        .
      </p>
      <p>
        Just like that, you can add your own components as stories.
        <br />
        You can also edit those components and see changes right away.
        <br />
        (Try editing the <code :style="code">Button</code> component
        located at <code :style="code">src/stories/Button.js</code>.)
      </p>
      <p>
        This is just one thing you can do with Storybook.
        <br />
        Have a look at the
        <br />
        <a
          :style="link"
          href="https://github.com/storybookjs/storybook"

        repo for more information.

        <b>NOTE:</b>
        <br />
        Have a look at the
        <br />
        <code :style="code">.storybook/webpack.config.js</code>
        <br />
        to add webpack
        loaders and plugins you are using in this project.
