title: Error - Nothing to commit on Git
body: <p>I am trying to commit my first_app onto Git.  I typed the following into the command lines (see below), but my output says that there is nothing to commit.  </p>
  
  <pre><code>new-host:first_app XXXXXX$ cd /Users/XXXXXX/rails_projects/first_app
  new-host:first_app XXXXXX$ git init
  Reinitialized existing Git repository in /Users/XXXXXX/rails_projects/first_app/.git/
  new-host:first_app XXXXXX$ git add .
  new-host:first_app XXXXXX$ git status
  # On branch master
  nothing to commit (working directory clean)
  new-host:first_app XXXXXX$ 
  </code></pre>
  
  <p>In a different terminal I had ran <code>$ rails server</code> to create my first_app.  Why is there nothing to commit? </p>
  
  <p>How can I fix this?  Thanks!</p>
