    <p>This is a UI component dev environment for your app.</p>
    <p>
      We've added some basic stories inside the <InlineCode>src/stories</InlineCode> 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 <NavButton onClick={showApp}>stories</NavButton> for a component called&nbsp;
      <InlineCode>Button</InlineCode>.
    </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 <InlineCode>Button</InlineCode> stories located at&nbsp;
      <InlineCode>src/stories/0-Welcome.stories.js</InlineCode>
      .)
    </p>
    <p>
      Usually we create stories with smaller UI components in the app.
      <br />
      Have a look at the&nbsp;

      &nbsp;section in our documentation.
    </p>
    <Note>
      <b>NOTE:</b>
      <br />
      Have a look at the <InlineCode>.storybook/webpack.config.js</InlineCode> to add webpack
      loaders and plugins you are using in this project.
