title: Is it possible to add just one page to existing sire project via PUG when the rest is written in simple HTML5?
body: <p>So I have a simple site at hand, written with <em>HTML5</em> and <em>Less CSS</em>. Now I have to add a market-page to it and I found a comprehensive guide on how to do that with <em>ExpressJS + PUG + MySQL</em>.</p>
  <p>But before I do that I would like to know whether I'll have to convert the whole site project into new structure or I will be able to simply add a market page to already existing project without generally changing it?</p>
