  <p>So, <code>master</code> got left behind.  Not sure how that happened.  Once I decided I was done with the branch that didn't work out I checked out <code>[7280b1f]</code> and continued from there.</p>
  
  <p>How do I fix this?  I this the infamous "detached head" issue?</p>
  
  <p>Does <code>master</code> have to be aligned with <code>HEAD</code> for optimal health of the repo?</p>
  
  <p>My workflow is super-simple.  This is just managing a single text file.  In the vast majority of cases it's:</p>
  
  <pre><code>git add .
  git commit -am "Some comment"
  </code></pre>
  
  <p>And that's it.</p>
  
  <p>I decided to try an idea and created a branch. When it didn't work out I checked out the root of that branch and went back to the <code>git add/commit</code> routine.  </p>
