title: Editing a git submodule
body: <p>Is this possible? Imagine I have projects Parent &amp; Child. Both are git respositories. Child is a submodule of Parent.</p>
  
  <p>Can I make edits to the version of Child that is inside Parent &amp; commit &amp; push them just like a regular repository?</p>
  
  <p>Or do I need a separate clone of Child somewhere that I make changes to?</p>
  
  <p>Thanks.</p>
