I wrote the bulk of this book throughout the whole of 2020 and in the first half of 2021. I used Visual Studio Code on macOS for most of the writing, although on rare occasions I also used Working Copy on iOS. OmniGraffle was used to create all the diagrams in the book. AsciiDoc was used to format the book and on the whole was excellent, with O’Reilly’s Atlas toolchain doing the magic of making a book appear on the other side.
