title: First time using node.js - "ReferenceError: node is not defined"
body: <p>I just installed node.js. 
  I tried writing node -v that should check the version - and it's not working. this is the output:</p>
  
  <pre><code> &gt; node -v ReferenceError: node is not defined

  <p>I opened it using git - command: <code>node</code> </p>
  
  <p>I tried running it using "Git", thought maybe that's the issue and I get the exact same output. </p>
  
  <p>I am using windows 8 if it's relevant - followed this tutorial till now: </p>
