title: Is 'rubyinstaller.org' the official website for ruby?
body: <p>I found two websites:</p>
  
  <p><a href="https://rubyinstaller.org" rel="nofollow noreferrer">rubyinstaller.org</a></p>
  
  <p><a href="https://www.ruby-lang.org" rel="nofollow noreferrer">ruby-lang.org</a></p>
  
  <p>Which of them is the official website, or can I just download Ruby from any of them?</p>
