When you launch HOI4, you'll notice a 'Mod Tools' button in the launcher. One of these is the ability to create an empty mod in mere seconds. While unfortunately Paradox hasn't given a lot of documentation about modding, they've given a lot of useful tools to help the modder get going. These series by The Iron Workshop give several tips on how to make several useful changes, and include a nice introduction on making new provinces.Īlong with these videos, the wiki page below shows a good list of sites you can access to learn coding or refer to resources. The playlist made by Paradox themselves are the canon resource, and while they cover several complicated schemes(new resources, province editing etc.) it's not organised or user friendly and I wouldn't recommend it for the fresh green modder.
The playlist by MrKmproductions is by far the most informative and helpful series on Youtube, and help you get quite a far way. These are some of the videos powerblo thinks are the most useful for starting off.
If you don't feel like learning modding from text, you can always receive visual guidance. The first few steps are a popular topic and various tutorial videos have been made on it.
