How can I best add a knowledge base to my store on Shopify?

Hello guys,

I read this article by Exposure Ninja: https://exposureninja.com/blog/what-knowledge-base-why-should-you-build-one/

I’d like to add a knowledge base to my store: https://proteinpackage.co.uk/

What’s the best way to go about doing this on Shopify?

Using an app or building pages on Shogun?

Thank you!
