title: YARD is not the same as RDoc?
body: <p>Correct me if I'm wrong, is <a href="http://yardoc.org/" rel="nofollow noreferrer">YARD</a> not the same as <a href="https://ruby.github.io/rdoc/" rel="nofollow noreferrer">RDoc</a>?</p>
  <p>It's not based on RDoc but a total rewrite?</p>
  <p>So if I'm using YARD, I don't have to bother with RDoc right?</p>
