title: how to include video in jekyll markdown blog
body: <p>I just started blogging using jekyll. I write my posts in markdown. Now,  I want to include a youtube video in my post. How can I do this?</p>
  
  <p>Also, I dont really like the pygments highlighting provided by jekyll by default. Is there anyway I can change  this to some other style? If yes, can you point me to some nice styles/plugins? </p>
