Request for Updated Guide on Relume Base Styling

I was onboarding one of our art directors sent him this way: https://www.loom.com/share/cd8fda5fc77749c0894ac438ed0072d3 and I noticed it's 2 years old and very basic. Given all recent changes with variables and what not, it would be great with a updated guide and also a more comprehensive deep dive into base styling with relume, like changing base background to something darker (he just asked me how, haha) and you know a guide where the end result have a bit more custom look and feel to it. That would be great! 🙂
