How do I get nginx to serve the "www." version of domain.com?

Hello everyone,

I downloaded a LEMP stack onto my server and I have gotten nginx to serve domain.com, but for the life of me I cannot figure out how to get nginx to serve www.domain.com.

Here is what the code looks like currently:

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        root /usr/share/nginx/html;
        index index.php index.html index.htm;

        server_name domain.com www.domain.com;

        location / {
                try_files $uri $uri/ =404;
        }

What change can I make to get www.domain.com to work?
