title: How to create a chrome extension to change the default tab
body: <p>I would like to create a chrome extension which changes my default tab in chrome browser. </p>
  
  <p>Inside the page I will put my favorite websites, which I think I can handle using HTML + CSS. My difficult part is how to make it become a chrome extension because I have never done it before.</p>
  
  <p>Can anyone give me some basic steps which I could start with?</p>
