The hordes version 1.2.0+ now uses datapacks to configure various parts of the mod, either by editing the default datapack located at config/hordes/data in your current minecraft folder, or adding your own to your world.

If you mess up the default datapack, or want to reset to default settings, make a backup of any important files stored in there, then delete the hordes folder from your config folder, and the mod will regenerate it on the next run.

Most datapack files use the json format, and I would recommend familiarizing yourself with it and using the website jsonlint to check syntax if you're ever unsure.

At some points in this wiki, you may see <identifier> listed, this is whatever folder you use for your custom datapack, which by default will be the mods id hordes.
