title: How do I run a node.js app that I installed with npm?
body: <p>So I installed Node.js on my Windows machine, opened up command prompt and typed</p>
  
  <pre><code>npm ethercalc
  </code></pre>
  
  <p>Lots of lines flew by and it seems ethercalc and its dependencies have been downloaded and installed. Now, how do I run ethercalc?</p>
  
  <pre><code>node ethercalc
  </code></pre>
  
  <p>returns a message saying it can't find file "ethercalc" in the <em>current</em> directory.</p>
  
  <p>Note: I'm completely new to node.js. I was very surprised that the official website does not contain basic "Getting Started" info.</p>
