title: How do I install the newest unstable NodeJS (e.g. 0.11.xyz) on Ubuntu
body: <p>I'm looking into playing around with Koa and I need to run the newest unstable version of NodeJS.</p>
  
  <p>Is there a simple <code>apt-get</code> or <code>npm</code> or even <code>node</code> call I can make to get the newest NodeJS version? </p>
