With the release of the latest expansion, I was wondering if there've been any major changes to modding custom cultures.

It's been awhile since any have been posted, and my numerous attempts in the past failed because I had no idea how to use the Mod Tools even with instructions.

I'd like to try again, but if the process has gotten more complex than before, is there a guide that's been updated to match the changes so that I have a better understanding as to how to navigate what I'm looking at?

There is no updated guide. The outdated guide from uncle is mostly still valid.

There have been some changes to naming, like: archive -> override; additional tab and renamed tab data -> content.

If unsure, you can jump on the amplitude discord and on the modding channel is happy to help.
