title: Create Submodule From A Few Folders in One Repo - Way To Track
body: <p>we have one big repo with code from last 10 year (Original Repo).</p>
  
  <p>We want to re-use some of this code with several other projects, mostly in a few folders from Repo A. So I would like to make a new Core Repo and have these new projects use it as a submodule.  Eventually can update Original Repo to use Core repo, but not initially.</p>
  
  <p>Ideally would like a link from Core Repo to Original Repo (for the folders that I decided to bring over), but don't want to Fork the entire Original Repo and bring in a bunch of extra stuff.  Would I need to do this?</p>
  
  <p>Other option is to make a new clean repo for Core Repo, and then do new commits of what I want in there, and then add a new Remote to be able to see changes - is this possible, if there's only a few folders?</p>
  
  <p>Any other ideas/options?  Using Azure DevOps git btw.</p>
  
  <p>thanks</p>
