title: Git: Where exactly is the "working directory"?
body: <p>I am going through some Git tutorials. The concept of a "<em>working directory</em>" keeps being mentioned, however, none of the tutorials or documents I read points out where or what this "<em>working directory</em>" is.</p>
  
  <p>I have thought that it was actually the <code>.git</code>'s parent directory, a.k.a the directory I run <code>git init</code> in. But the video tutorial I am watching talks about the state of <em>nothing to commit</em> and "<em>working directory clean</em>":</p>
  
  <blockquote>
    <p>In fact you can actually make a copy of the repository, and make that
    copy so that it does not have a working directory, this is actually
    called the bare clone. This is actually what GitHub uses.</p>
  </blockquote>
  
  <p>If my understanding of the "<em>working directory</em>" is correct, how can a repository not have a "<em>working directory</em>"? And what does it mean, when it says that GitHub uses a "<em>bare clone</em>"?</p>
