News Sitemap for Ghost

I am sorry if this has been already answered. I have recently migrated my website from Wordpress to Ghost. Everything is perfect! But I have one problem: I am new to Node.JS and I have absolutely no idea how I can implement a news sitemap for my website. Can anyone please point me in the right direction?

Website URL: https://hackhex.com/

Best regards.

Edit:

Nevermind, I figured it.

  1. Add this to your route.yml:

    /news/sitemap/:
    permalink: /news/sitemap/
    template: news

  2. Add news.hbs to your theme folder:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:news="http://www.google.com/schemas/sitemap-news/0.9"> 
	{{#get "posts" limit="3"}}
	{{#foreach posts}}
	<url> 
		<loc>{{url absolute="true"}}</loc> 
		<news:news> 
			<news:publication> 
				<news:name>Hack Hex</news:name> 
				<news:language>en</news:language> 
			</news:publication> 
			<news:publication_date>{{date format="YYYY-MM-DD"}}</news:publication_date> 
			<news:title>{{title}}</news:title> 
		</news:news>
	</url>
	{{/foreach}}
	{{/get}}
</urlset>
