title: sendgrid make test throws errors
body: <p>I'm running node on my vps server. node is at my root, my app.js with node_modules (express, socket.io) are in /home/vps/public_html/</p>
  
  <p>when following github readme for setting up sendgrid i run into trouble:<img src="https://i.stack.imgur.com/GYOP9.jpg" alt="sendgrid github error"></p>
  
  <p>config.js is not live by the sounds of it as when I run sendgrids simple code example if i</p>
  
  <p>a.) refer to config.js by doing:</p>
  
  <pre><code>var sendgrid=new SendGrid(user,key);
  </code></pre>
  
  <p>node kills its self because user is not defined.</p>
  
  <p>b.) bypass config.js by doing:</p>
  
  <pre><code>var sendgrid=new SendGrid({user:'my_user_name',key:'my_password'});
  </code></pre>
  
  <p>I get console.log(message) of [ 'Permission denied, wrong credentials' ]</p>
  
  <p>here is another image this one is of my public_html structure:<img src="https://i.stack.imgur.com/cLWV7.png" alt="public_html"></p>
  
  <p>does any one know how to activate this config.js?</p>
  
  <p>Should I have installed node.js into my public_html in the beginning?</p>
