It’s every bit as confusing as you’d think it was. Especially if you’re doing it for someone else! I’m practicing on myself first to see if it works at all and then we’ll see.
It’s good to say “yes” and then learn something. Especially something as useful as this. I’m trying to make Woocommerce work. The issue is testing. As I don’t want to actually pay for something without knowing if it works.
