I’ve read about as much as you and it does seem to follow it fairly well. The TV show actually got me into reading the books, which have been fun to read.
It’s a timeline approach. So, I just enter notes for each day. I’ve developed a habit of just putting things down when I need, including random stuff, links to Slack conversations, etc. I then use tags to bind things together, and there are a couple of plugins in use.
Yes, this!
