title: How do I undo a checkout in git?
body: <p>I just checked out an earlier commit from my local git repo. I haven't made any changes to it, I was just looking at it. Now I want to go back to my latest commit - how do I do that?</p>
  
  <p>The exact command I used to check it out:</p>
  
  <pre><code>git checkout e5dff6b3c5d704f9b598de46551355d18235ac08
  </code></pre>
  
  <p>Now when I type git log, at the top I see this checked out commit, but none of my later commits. Did I accidentally delete those? </p>
