title: Untrack folder locally in git and push to production without deleting
body: <p>I have a folder <code>images</code> which used to be tracked and which i untracked using:
  <code>git rm -r --cached images</code>.</p>
  
  <p>I also added <code>images/</code> to my gitignore. However I am afraid that when I commit and pull on my production server, the images folder will be deleted. The reason is because the github app actually shows the files are deleted.</p>
  
  <p>So how do I prevent locally deleted, then untracked and ignored files to not be deleted on the production server on <code>git pull</code>?</p>
