Newbie question

I am new to nginx, so sorry for stupid question ...

I configured some apps behind it, like for example added a block to /etc/nginx/sites-enabled/default:

## Emby ##
location /emby {
rewrite /emby/(.*) /$1 break;
proxy_pass http://127.0.0.1:8096;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#auth_basic "Restricted";
#auth_basic_user_file "/etc/nginx/.htpasswd";
}

So now I can I open it as <domain>/emby

Can I customize it to be emby. <domain> or other name?

Thx
