title: Alexa Nodejs sdk - What does withSimpleCard() do?
body: <p>I am following the alexa nodejs sdk <a href="https://github.com/alexa/alexa-skills-kit-sdk-for-nodejs/wiki/Developing-Your-First-Skill" rel="nofollow noreferrer">tutorial in amazon</a></p>
  
  <p>The sample code has this line in all the responses - </p>
  
  <pre><code> .withSimpleCard('Hello World', speechText)
  </code></pre>
  
  <p>I checked the function definition file, it says : </p>
  
  <blockquote>
    <p>Renders a simple card with the following title and content</p>
  </blockquote>
