  <p>I tried to add intro tour for my application with <code>reactour</code>.
  And when I added the package 'reactour' in my application it asks for <code>@types/reactour</code> and I added that too.
  But still facing some package depending issues.</p>
  
  <p>I added these..</p>
  
  <pre><code>`"dependencies": {
      ...

      ...
  }`
