title: Git add not adding files
body: <p>when I try to git add my files, I typed </p>
  
  <pre><code>git add &lt;insert file names here&gt;
  </code></pre>
  
  <p>That works correctly. However, when I try to do </p>
  
  <pre><code>git commit -a
  </code></pre>
  
  <p>My git repository tells me that it's empty. What is outputted is:</p>
  
  <pre><code># On branch master
  # Untracked files:
  #   (use "git add &lt;file&gt;..." to include in what will be committed) 
  #
  &lt;insert name of files here&gt;
  
  nothing added to commit but untracked files present (use "git add" to track)
  </code></pre>
  
  <p>Might anyone know the solution to this? Thanks.</p>
