title: ngrok command not found
body: <p>I'm trying to install <code>ngrok</code> (which I've been using for a while on Windows with no issues) on my 1 week old yosemite and these are the steps I've followed so far.</p>
  
  <ol>
  <li><p>Downloaded ngrok from here <a href="https://ngrok.com/download" rel="noreferrer">https://ngrok.com/download</a>.</p></li>
  <li><p>Unziped the file and copied the Unix Executable File into
  application.</p></li>
  </ol>
  
  <p>Now from what I understand I just need to open the terminal, move inside the application folder and write <code>ngrok http 80</code>. The result of this is "command not found".</p>
  
  <p>I've even signed up at the <code>ngrok</code> website and run from terminal the command <code>./ngrok authtoken "blablabla"</code> and the result is "No such file or directory"</p>
  
  <p>Can anyone tell me how to proceed to be able to activate the tunnel with <code>ngrok</code>?</p>
