how to serve index page from django instead of nginx static index page option - gunicorn

Question

I am trying to deploy my webapp using NGINX-gunicorn-Djngo.The problem is when I open a root url(eg. www.xyz.com) in browser it shows default welcome page of NGINX but I want to serve my index page through django using proxy_pass.
when I am opening www.xyz.com// it works fine as the url matches with location block wiht pattern "/".Please suggest how can I make nginx redirect www.xyz.com to my gunicorn server.
find below my nginx.conf
