title: Git commit opens blank text file, for what?
body: <p>In all the Git tutorials I've read they say that you can do:</p>
  
  <pre><code>git init
  git add .
  git commit
  </code></pre>
  
  <p>When I do that I get a big text file opened up. None of the tutorials seem to address this, so I don't know what to do with the file or what to put in it if anything.</p>
