HOW?
Json Things works via Thingpacks, which are similar to resource packs or datapacks. Thingpacks contain thing jsons, along with resources and data.
To install a thingpack, place it in the thingpacks directory in your game installation, or drag&drop it in the Json Things configuration screen.
You can also place a resource pack or datapack there, since the thingpack loader also adds the packs to the list of resourcepa ls and to the list of datapacks. Yes this means this mod works as a global datapack loader, even if unintentionally!
Documentation
If you want to create your own thingpacks, you can find the official documentation here. It's a bit barebones right now, but it describes the json files' structure as completely as I could.
Sandwood: A Json Things example pack
You can find the Sandwood example as an additional file in the release (look for the "+1 More" text in the Files page). I will try very hard to keep the sandwood example updated with the latest features, so it can work as a reference.

Can I use this in <X>?
Yes. Unless <X>'s license is incompatible with this mod's, which is unlikely.
