title: Django External App Installation
body: <p>I didnt find any tutorial on adding an existing app to a Django project.
  Can anyone helps me out ?
  For example I want to add this <a href="http://code.google.com/p/django-friends/" rel="nofollow">http://code.google.com/p/django-friends/</a> to my existing project.
  What are proper steps ?</p>
  
  <p>I tried python setup.py install, it went well but nothing seems to change in my interface.
  Im noob of Django so please bear with me.</p>
