title: Command to download latest version of nvm?
body: <p>I am trying to install the latest version of <code>nvm</code> so (<a href="https://davidwalsh.name/nvm" rel="nofollow">per this article</a>) I ran:</p>
  
  <pre><code>nvm install 4.0
  </code></pre>
  
  <p>It worked. But I want to make sure I install the latest version of nvm as they might have released a newer version after the article was written.</p>
  
  <p>Is there a command I can run to download the latest version of nvm?</p>
