title: Why aren't my new files appearing in my GitHub repository?
body: <p>I have created a repository, now I have worked on about 5 source files but they dont appear online. How do I upload them/make them show online.</p>
  
  <p>Secondly, how do I allow other people to use the repository? What I mean is, the project is a four-person thing so how do the others join and how do I control uploaded files?</p>
