title: git untracked files - how to ignore
body: <p>When I run <code>git status</code>, I see the "Untracked files" section has many files (some with a "." extension.)</p>
  
  <p>I don't think I have to do anything, but it doesnt look good to see these files whenever I run <code>git status</code>. Is there any way to not to see these files?</p>
