title: View or Test README files *md in a browser prior to pushing to an online repository for rendering
body: <p>Is there an application or way to render a README.md file in a browser on or offline?   I am learning Markdown, and want instant feedback on some of my writing, as sometimes I forget a space or a blank line to achieve what I want, and it is cumbersome for me to commit and push to GitHub to see its rendering, not to mention the insane number of commits I'm creating for a small change.</p>
  
  <p>Some have suggested setting up a PHP environment in your own server or virtual server, but I don't know how to do that (yet).  I was thinking of an extension that if you opened an *.md file in your browser (I use Chrome predominately, but occasionally FF), it would look the same was as the frame in GitHub.\</p>
  
  <p>I use TextMate and Sublime Text 2 to write the markdown, maybe they have a function I haven't seen/found on their site?</p>
