title: Why is there "nothing to commit" after I added my new directory?
body: <p>Ok this is really frustrating me. I'm used to working with SVN, and am new to git. I had a folder called X in git already. A collobarator made changes to X and commited it, and I updated it. I made changes to it, and now I want to save it as X2 as a new folder. So I duplicated the X folder locally, and now I want to add this to github. So I did </p>
  
  <pre><code>cd X2 
  git init 
  git add X2 
  git commit -m "changes" 
  git push origin master
  </code></pre>
  
  <p>I also tried being in the parent directory where both X and X2 are located, then git add X2 and commit and push, but I keep getting "nothing to commit".</p>
  
  <p>What am I doing wrong?</p>
