title: Can't get new files from git branch - 'Already up-to-date'
body: <p>I'm new to git and am struggling with this.</p>
  
  <p>I need to grab some files from a Github branch (not even sure if this is the right terminology).</p>
  
  <p>I tried: </p>
  
  <pre><code>git pull someones-project/feature/branch-123
  </code></pre>
  
  <p>and</p>
  
  <pre><code>git merge someones-project/feature/branch-123
  </code></pre>
  
  <p>and got <code>Already up-to-date</code> for both.</p>
  
  <p>But it's not up-to-date. I can see files on Github that are missing from my local.</p>
  
  <p>Can anyone point me in the right direction here?</p>
