title: upload files to a branch in github
body: <p>I know there are hundreds of tutorials out there on this, but I couldn't figure where to start. 
  I am using a MAC and am on a remote system which runs Ubuntu 14.04.
  What I want to do is upload folders to my organization's github repository. There already exists a repo, and I want to create a branch and upload my files and folders in that branch.</p>
  
  <p>I tried doing</p>
  
  <pre><code>git branch branch_name
  git checkout branch_name
  </code></pre>
  
  <p>However the branch does not show up on the webpage. I also tried creating a branch from the webpage, but I dont know how to upload files to it. I am also not sure how to actually navigate to the repository to which I want to upload.</p>
  
  <p>Please give me instructions as to how I could go about doing this. </p>
  
  <p>Thank you!</p>
