title: How to make a pull request from the repository I forked to the original
body: <p>Steps I've followed: Set up git and account on github, forked a repository for assigments I have to do, and currently following this guide: <a href="https://help.github.com/articles/creating-a-pull-request/" rel="nofollow">https://help.github.com/articles/creating-a-pull-request/</a></p>
  
  <p>I forked succesfully and modified a file in MY repository, which is a fork of the original. I now want to pull the changes to the original so that they get approved or denied.</p>
  
  <p>The problem is I don't understand the concept and nothing shows up, following those steps, which makes sense because I try to pull into the original master and it tells me there are no differences so there's nothing to update (because the change is in my forked repository).</p>
  
  <p>What concept am I missing? Because right now I'm not even sure the operation i should do is a pull since when looking for more info nothing shows up.</p>
  
  <p>Thanks in advance.</p>
