Very good guide! One mention: please insert a chapter talking about the differences between PUBLIC and PRIVATE LN nodes. The whole guide you've talk is about public nodes and you missed out a lot to talk about the private ones.
I will give some hints here: #486306
I do mention the possibility of opening private channels, here: https://docs.megalithic.me/running-a-full-node/how-to-open-channel#public-vs-private-channels
