I am using the default config while adding the specific directory with nginx installed on my ubuntu 12.04 machine.
server {
#listen 80; ## listen
By default the static data, when you install the nginx, will be in /var/www/html. So you can just copy your static folder into /var/html/ and set the
root /var/www/
in ngix.conf (or /etc/nginx/sites-available/default)
This worked for me on ubuntu but I guess it should not be much different for other distros.
Hope it helps.
