I wrote this in 2021, finished in November, and it was pretty much obsolete by the end of December. Things weren’t getting any better, and I fought with the idea of publishing it for more two years.
I have finally decided to publish it. It is still worth reading, and it can be used as a baseline.
I, and others, can build on it.
I started out categorizing the lessons learned, and most of them fit neatly into chapters. Towards the end, however, some of the didn’t fit neatly and I was just listing lessons learned.
