title: How do you "check out" code?
body: <p>I've never really worked with a lot of people where we had to check out code and have repositories of old code, etc. I'm not sure I even know what these terms mean. If I want to to start a new project that involves more than myself that tracks all the code changes, does "check out" (again, don't know what that means), how do I get started? Is that what SVN is for?  Something else? Do I download a program that keeps up with the code?</p>
  
  <p>What do I do?</p>
  
  <p>It will all be in house. No Internet for storing code.</p>
  
  <p>I don't even know if what I am asking for is called source control. I see things about checking out, SVN, source control, and so on. I don't know if it is all talking about the same thing or not. I was hoping to use something open source.</p>
