How do you prep your Homebrew/APs?

I am a new GM of Pathfinder 2e and my Group and I voted Kingmaker P2 to be our first Adventure Path to play through after we finish the Beginner Box (exquisite material!).

Now I have my Obsidian.md vault set up with tons of plugins for managing encounters, creatures and rules and pull the content out of the Kingmaker P2 Adventure Path while trying to keep it structural sound (each chapter on its own, with cross linking between Quests and Characters etc.)

How do you guys do it if you prep a campaign, adventure paths or even just your worldbuilding? What tools do you use and how detailed do you write your notes?

*On a side note: If this post isn't in the correct place, so I apologise as this community is the only one I can see from my instance (coming from feddit.de) on your instance (pathfinder.social) also I am pretty new to lemmy all together. *
