Config based patch management for Subnautica and Subnautica: Below Zero

QMods is available for several mod-hosting websites. Typically they will install QMods for you as a dependency of whichever mod you download.

Subnautica

• Thunderstore
• Nexus

Below Zero

• Thunderstore
• Nexus

Extract the relevant zip file into the Subnautica directory. There are several zip files, one for each version of the game.

• Subnautica - SN.STABLE
• Below Zero - BZ.STABLE

You will end up with a folder like this:

Subnautica
  - QMods/
  - BepinEx/
  - doorstop_config.ini
  - winhttp.dll
  - Subnautica.exe 

Each mod should have one folder in the QMods directory.

Each mod needs to specify that it's compatible with Nitrox in their "mod.json" file.

{
  "Id": "MyMod",
  "NitroxCompat": true
}

Mroshaw created an excellent guide to get started.
