Awesome, I added a few minor comments 👍 Also, what are we going to do with the old design docs? Maybe create a new directory for them called old?

Well I assumed here that we won't write ADRs for old decisions. I wouldn't also call them old since they are up to date with the current architecture. I don't mind having them laying around in the docs folder, but I'm open to suggestions.
