title: Change .Rmd file to .md file
body: <p>How do I change an .Rmd file to an .md file, that I can then push to GitHub? I have knit to HTML</p>
  
  <p>Is it possible to do this by something as simple as changing the file extension to ".md" and doing a save as? Any insight into what the differences are amongst these types of files would be so helpful! </p>
  
  <p>Also, how different should an .Rmd and .md file look when opened?</p>
  
  <p>Thank you!</p>
