Infinity scroll Crave theme with "View more" Button

[tommyz23]

Hello,

I'm trying to add an infinity scroll to my featured collection and collection pages, but want the ability to have the "Load more" Button to display more products.  Does anyone know which code to add and which pages to add them to?  I'm kind of stuck here.  This store is using the "Crave" theme. 

I'm assuming I'd add code to the theme.liquid , the featured-collection.liquid and maybe collection-list.liquid

Thank you,

Tommy
