I've been following this tread and looking to implement this into our (Brine template) website. I have to admit i'm a bit lost on where to start since the thread and code has several iterations.
Ideally we would like to use variant within a given product listing, each linking to a different external URL when the add to cart button is clicked for that variant.
Where are the most recent instructions and code located, I saw a mention of a GitHub, but no link to it.
Any help to get this off the ground would be awesome .
