title: Where to set value of liveServer.settings.port in live server extension of visual studio code
body: <p>I am working on Angular7 with visual studio code editor 
  URL: <a href="http://localhost:4200" rel="noreferrer">http://localhost:4200</a> (Working fine)</p>
  
  <p>But, I installed extension <strong>Live Server</strong> and when I click on Liveserver icon its giving me the error </p>
  
  <blockquote>
    <p>"Error on port 5500. Please try to change the port through settings or
    report on GitHub."</p>
  </blockquote>
  
  <p>So, I opened the <strong>File->preference->Settings->LiveServerConfig</strong> and 
  tried to change port in settings.json file </p>
  
  <pre><code>{
      "typescript.tsdk": "./node_modules/typescript/lib",
      "tslint.enable": false,
      "liveServer.settings.multiRootWorkspaceName": "QiwkCollaboratorTool",
      "liveServer.settings.root": 0  // New added line
  }
  </code></pre>
  
  <p>Am I going into right direction or am I missing something ? I am not sure how to change the port number 5500 to 0 as I want random port number.</p>
  
  <p>Thanks in advance!</p>
