Like if, say, I wanted to edit guard towers to have two guards. How would I actually go about doing that? I know there's an example mod that does this but the example mod doesn't actually teach anything. It's just there, already finished, proving that mods are possible but doing nothing to show me how to make one. How to access the game files or edit them. And the PDF certainly didn't explain anything to get me going. The author seems to assume that the reader is already familiar with this stuff, which is strange since if I was familiar with this stuff then I wouldn't need a walkthrough.
