title: Setup Jinja2 in Django Project
body: <p>Newbie question, yet I cannot find a sufficient step-by-step instruction on Jinja2 official website or by googling. </p>
  
  <p>My current Django project is halfway done, and I cannot stand not able to use queryset filter in Django template anymore. So decide to switch to Jinja2. </p>
  
  <p>What I have done: pip install jinja2 to the virtualenv. Then I tried to use Jinja syntax in my template files, which fails.. apparently and sadly</p>
  
  <p>What else do I need to do to make Jinja2 work?</p>
