title: What is Bootstrap?
body: <p>There are a lot of questions here related to Bootstrap. I see a lot of people using it. So I tried to research it, and I found the <a href="http://getbootstrap.com/" rel="noreferrer">official Bootstrap site</a>, but there was only a download section and a few words after that. Nothing that explains what is it for... I just understood that it is a front-end helper. I have tried to find something by Googling, but found nothing specific. Everything I found is related to the computer science definition. </p>
  
  <p>So, my questions are: </p>
  
  <ul>
  <li>What is Bootstrap at all?</li>
  <li>What is it used for, and how does it help front-end development?</li>
  <li>I would also like some more details explaining it.</li>
  </ul>
