As in any modding community, tools are required in order to get gamefiles or inject your modded files into the game.
Both tools are nessecary in order to mod.
Editing software is as the name suggests here to modify said gamefiles. Therefore you need 2D, 3D and maybe Coding software. Behind each Button, you see what files you can edit with those tools from the selected category, skip those which you currently don't need.
Sidenote: There are plenty more tools, but since this can get overwhelming we skip those for now, we recommend using the tools which suit your current goals and those required in their specific guides.
The guides down below are recommended for beginners up to advanced modders. Don't be scared about the load of informations in our guides. Some might look scary but you'll get the hang of it quickly!
We offer alot of different guides which are more specific to certain problems. Please make sure you check them out if you're having any trouble.
