title: How to start working with pug?
body: <p>I know and use html, js, less. But I'm newbie in nodejs, pug/jade. Just trying to understand how it works.</p>
  
  <p>I've read many tutorials about pug/jade's syntax but I haven't find a tutorial how to work with it.</p>
  
  <p>Where must I write a code?
  How to open it in browser?
  What I need for that?</p>
