title: How to preview rails?
body: <p>A website is shared to me on github. I'm working on it, but I can't do modifications on the actual site page yet. I need to see how the changes I make look like.</p>
  
  <p>How can I have a live preview from rails? I was used to use xampp for the html/css stuff. Is there anything similar to that? If not, what are my choices?</p>
