    listen 80;  # Listen on port 80, the default HTTP port
    server_name localhost;  # The server name, here it is set to localhost

    root /var/www/html;  # The root directory where files are served from
    index index.html index.htm;  # The default files to serve

    location / {
        try_files $uri $uri/ =404;  # Try to serve the requested URI, if not found return a 404
    }
