title: Firebase Hosting set up issue
body: <p>I'm just trying to do a simple set-up for hosting on firebase. I'm following the instructions at (<a href="https://www.firebase.com/docs/hosting/guide/deploying.html" rel="noreferrer">https://www.firebase.com/docs/hosting/guide/deploying.html</a>) but I'm missing something because I keep getting an error of:</p>
  
  <p>'firebase' is not recognized as an internal or external command, operable program, or batch file."</p>
  
  <p>What I've done:</p>
  
  <ol>
  <li>Installed nodejs. </li>
  <li>Set PATH = to C:\Program Files\nodejs; via control Panel</li>
  <li>in cmd: <code>cd C:\Program Files\nodejs</code></li>
  <li><code>npm install -g firebase-tools</code></li>
  <li>changed directory to folder with my html files</li>
  <li>tried running both <code>firebase app init</code> and <code>firebase init</code> neither of which work and give me the same error</li>
  </ol>
