title: Github: Why do I need it?
body: <p>I am still quite unsure how to use it, but I just downloaded Git and I was setting it up according to their <a href="https://help.github.com/articles/set-up-git" rel="nofollow">web page</a>. The section on password caching says if I don't have to enter my password every time, I can use Github for Windows. I was confused so I found a question here asking "what is github anyway?" and the answers say it's a website or it's web hosting. So I clicked the Github for Windows link on the how-to page and next thing I know I'm downloading an .exe file. </p>
  
  <ul>
  <li>If Github is a website, why do I need an .exe file? </li>
  <li>Is the only benefit to not type in your password?  </li>
  <li>How does Github relate to Git Bash?</li>
  <li>Are Git and Git Bash the same thing?</li>
  </ul>
  
  <p>P.S. I have 2 computers, 1 is XP and the other Win7. The downloads I'm talking about were on the XP but I will also put it on the 7 if I can determine that I need it.</p>
