title: How do I start using source control with an existing project?
body: <p>So I'm working on my first website in Eclipse. It is very simple only shows some text and an input box currently that does nothing, all this eclipse stuff is in my project folder. I've set it up to use Apache Tomcat 9 which is also in my project folder.</p>
  
  <p>Now I think that I shouldn't just push my top level project folder as if I do this, everytime I open up the project in Eclipse, Sourcetree will show 50 or so files modified (.metadata files and such), so I'm guessing that I shouldn't have pushed these to start with.</p>
  
  <p>I've since reset all my commits and am now wondering which files are necessary to upload to github?</p>
