Modding, or creating mods, is the act of modifying the behavior of the base game (often referred as vanilla), either for personal use, or to release publicly to other players. As for all Paradox games, Victoria II is moddable to a great extent.
Motivations of modders may vary widely: better translation to native language, more events or decisions, better map, major overhaul, etc.
Modding is not magic or heresy, anybody can learn to build a mod, and this guide is intended to lower the entry barriers to the world of Vicky 2 modding.
Yet, however good the documentation, there is still a learning curve to it, and it cannot replace the need to read some working vanilla code, and do lots of trial & error experimentations!
