+This data pack is used to kill any persistent or "unclean" zombies that have picked up items and now won't despawn.
+This is done by using the "/trigger cave_glow" and "/trigger cave_cleaner" commands in spectator mode.
+Want to see it in action? Check out Xisumavoid's video on the pack and how it's used: https://youtu.be/NpOszQWKC8s?t=119
+
+This datapack was originally created by Grant from the Vanilla Tweaks team and was used on the Hermitcraft Season 8 world.
+BUT, this is an unofficial—and therefore unsupported—version of the datapack, as I have modified the files to update and improve the pack to the latest version.
+
+If you would like to download the official (and outdated) version of the cave cleaner datapack, you will find it in the datapacks folder here:
+https://download.hermitcraft.com/hermitcraft8.zip
+
+Why isn't there an official version of the Cave Cleaner datapack?
+	Quote from Grant: "A lot of people would want to configure it (like by changing the items, radius, etc), and I don't like requiring people to go into the data for basic configuration.
+	Since that isn't very user-friendly, and we wouldn't want to be obligated to give lots of people support for going into the files to configure it either, or have to write FAQs for it."
+
+Could it not be done through an options menu?
+	Grant: "Not really, since it's based on tags. Those can only be modified using JSON, not commands.
+	We could, hypothetically, implement something that is based on commands but it would be really messy and/or inefficient."
+	(Clearly he decided it was not in his best interest)
+
+
+
+Thanks to Grant from the Vanilla Tweaks team for creating the original datapack and pointing me to where I could find the files. You can find some of his other work here:

+*** PLEASE DO NOT CONTACT GRANT OR ANYONE FROM VANILLA TWEAKS ASKING FOR SUPPORT REGARDING THIS DATAPACK ***

+I have no affiliation with Hermitcraft or Vanilla Tweaks, and likely never will. I am providing this tool as a public resource so the player base can keep their worlds and servers lag-free.
+If any members of Vanilla Tweaks or Hermitcraft have issues with this pack, please contact me at one of my socials referenced below. Thank you.
