I enjoyed this informative series (I skipped only the article on setting up on a DVD or USB flash drive). The tone is enjoyable too: that of a developer who has spent time working through many difficult corners and wants to share useful tips based on their experience, but makes no claims to omniscience. Needless to say, this is a refreshing change of pace from the AI-"enhanced" fare that's so common nowadays.
I did notice that the link in the main "menu" to part 5 actually goes to part 4, but you can still get to that final part via the "next part" link from the end of part 4.
