There’s instructions on how to do it manually included but not recommended unless you know what you’re doing. If doing the manual way it appears that you need to put this pack before terralith to work correctly. I am also not updating the manual method as it's too messy for me to work with or suggest so do so at your own risk.
A version of Cavernous is embedded inside so just grab the datapack and the mod patched and you should be good to go.
If not using a mod/datapack that is adding custom biomes with an overworld.json(such as Terralith) you'll probably need the Fix to make the biomes work correctly.
Noteable packs that will need this fix is if you're only using Geoliphic, Tectonic, or WWOO WITHOUT Terralith.
Simply a port of Thxlotl's Cavernous to convert it to make use of EnderTurret's Patched to work with other mods.
Tested with Terralith(2.5.9), Tectonic/Terratonic(3.0.0), and WWOO(2.44).
Technically compatible with 1.20.1(for version 1.5, no higher)just some of the items might not work right but the generation side should be fine.
Massive credit to Thxlotl for the amazing work on they did on Cavernous and to EnderTurret for making this possible and helping me create the patches correctly. Also credit to SlideDrum for figuring out how to fix the overwriting of Terralith biomes. I was just the middle man to put everything together and post it.
The discord linked is Thxlotl’s and has a channel for #compatibility if you have questions.
I disabled geysers in my version as I wasn't a huge fan of them though feel free to enable them yourself as they're still in the pack just diabled by default. I also disabled the intro message because I find them to be annoying but the same stuff I think is still true about needing command blocks enabled for some stuff to work.

Updated to Cavernous 2.2.2 and Minecraft 1.21.5
Cavernous needs to be above Terralith in the load order(in the integrated MC Datapack display, not sure about a .json load order for Paxi)

A fix for if you're not using Terralith or another datapack that adds a custom overworld.json file for 1.21.4.
Needs to be higher in the load list than the main(so lower on the in game datapack list or higher on a datapack loader like Paxi)

Just a version rerelease of 1.21.1
If need be I can readd the fix file for this one though the 1.21.4 version should be close enough to work.

Updated to Cavernous 2.2.1 as well as 1.21.4. Same as last time the "Resource Pack" is actually a datapack that adds files required to make it work if you're not using a mod that changes the /dimension/overworld.json or /worldgen/noise-settings/overworld.json. Shouldn't be necessary unless you're not using teralith.

Updated to Cavernous 2.1.3 to support Minecraft 1.21
Also figured out an issue that was causing the pack not to work if you didn't have a datapack that had an overworld.json to patch by adding a separate datapack with the vanilla values to load separately.
The "resource pack" is actually this vanilla datapack to allow the patching to work correctly if you don't meet the previous condition.

Fixed a cruical bug that stopped triggers from working correctly. Also cleared up the instructions a little bit as to how to do the manual install.

Changed pack.mcmeta to reflect the correct version number. Also as for now Patched has an issue with the latest version of Fabric API(0.96.11) and only works with 0.95.1 for now. As another side-effect, Sodium needs to be downgraded to 0.5.7
