Question on Adjusting Relume Style Guide in Webflow

Hey everyone! Quick question here around style guide as well. I'm following this guide here and it mentions things like 'Base colour System' and other bits but after copying the Relume Style guide into Webflow I dont see any of this (Tutorial) Instead I'm finding 4 variables sections with way less styles than in the Tutorial video (see video attached) Any one an idea how to approach this? Where would I add and adjust all those bits and bobs to ensure we are starting from a super clean project? Thanks!
