title: Git: Revert to previous commit status
body: <p>I'm confused. I want to go back to a previous commit that I identified in "git log".</p>
  
  <p>But when I do "git checkout ", I don't get said commit. Nothing changes.
  It tells me I'm in detached HEAD mode, but the files I want are not there.</p>
  
  <p>What the eff am I doing wrong?</p>
