From Vintage Story Wiki

This is because nearly every feature of the game relies on the usage of JSONs, which are text documents that utilize a flexible, easy to read format. You can open these files with any text editor, and with just a little bit of practice you can learn how to format them to avoid errors. The best way to learn this is to study the existing JSONs that are visible to anybody who has the game installed. To do so you'll need to locate the Vintage Story Assets folder, which you can learn about at the Asset System page.
In addition, here is a 12 minute video that will teach you why json is used, and the basic syntax, making it easier to understand the rest of the documentation.
