title: Git - Push subfolder to different repository
body: <p>I have a big repository with many files and projects. One of the sub-folders in this repo has to be a new, separated repository.</p>
  
  <p>I don't need to preserve history in the new one, but I have to be able, at any time, to update new repo with changes from the original repo.</p>
  
  <p>The idea is that the old repo is a private, internal gitlab and the new repo is a public repo for deployed project.</p>
  
  <p>How can I do this?</p>
