title: Is There a Markdown Syntax for Titles, Author, Etc?
body: <p>I just saw a video on Markdown which uses a percent sign (%) to add a title and author to a document.  Here is the video clip (strating from the relevant section):  <a href="https://youtu.be/hpAJMSS8pvs?t=5m30s" rel="noreferrer">https://youtu.be/hpAJMSS8pvs?t=5m30s</a></p>
  
  <p>I have not been able to reproduce this feature, though (I've tried in different markdown editors -- like StackEdit).  </p>
  
  <p>Is this a different version of Markdown?  Do I just need a different editor?</p>
  
  <p>In short, any idea how to do this?</p>
  
  <p>Thanks.</p>
