Modding (Factorio)

I'm trying to make my own mod, but I'm running into a lot of problems. Maybe someone decides to create a guide for modders? Mostly interested in questions related to scripts and creating a GUI, as well as how to accurately determine the collision_box, selection_box so as not to manually adjust. There are a lot of good ideas, a lot of useful things could be done, we just need answers to questions. If someone is good at this, please write in a personal.

UPD The game appeared on Steam, out of 16K reviews it has 98% positive. This is a very successful launch. If there are those who are engaged in modding, then I would like to cooperate to solve some issues.
