title: Git repo inside repo
body: <p>I want to clone <a href="https://github.com/getyouridx/pychargify" rel="noreferrer">https://github.com/getyouridx/pychargify</a> into my django project, and will need to pull updates from time-to-time.</p>
  
  <p>Just for clarification, could I simply write a gitignore from the root directory of the django project e.g. <code>.gitignore: pychargify/.git</code> or are there other pitfalls I should be aware of?</p>
