title: How can I combine two commits into one commit?
body: <p>I have a branch 'firstproject' with 2 commits. I want to get rid of these commits and make them appear as a single commit. </p>
  
  <p>The command <code>git merge --squash</code> sounds promising, but when I run <code>git merge --squash</code> my terminal just brings up options for the command. What is the correct command? </p>
  
  <pre><code>Commit 1:
  Added 'homepage.html'
  Added 'contacts.html'
  
  Commit 2:
  Added 'homepage.php'
  Added 'homepage.php'
  Deleted 'homepage.html'
  Deleted 'contacts.html'
  </code></pre>
