Can someone please help me with the submission process?  I am new to github.  I was able to Fork and then clone the repo, I created my own directory and wrote my code.  The last step says "Make a pull request on the master branch to submit your entry"  I'm not sure how to do that.  In the command window I do git pull origin master and it just says Already up-to-date.  This makes me think I'm doing something wrong.  Plus I see my code in my repo, but not in the main contest repo.  Thanx in advance.
