The json library is simply a third-party library implementing the JSON file format. This library is created by rxi.
Because daochook does not make this library, the documentation here will instead link to its official page.
You can find more information about this library here: https://github.com/rxi/json.lua
Note: This library is not recommended to be used for general purpose addon configurations.
Instead, you should make use of daochook’s settings library if you need addon configurations.
This library should only be used if you absolutely need support for JSON files.
