Sorry... Core Keeper console editions do not support modding, and probably never will.
See this message from the developers:
... there will not be any mod support on consoles at launch, and we will most likely never support mods on consoles in the same way we do on PC. The platform owners (Sony in this case) have strict requirements for all games that are released on their consoles, and there is no reasonable way to comply with them if players can modify the game to any meaningful extent. If there are mod features that you would like to have on consoles, feel free to post a suggestion in 📋-feedback-suggestions to potentially have it added to the main game 🤠 -Herman on the Core Keeper discord
Dedicated servers do not have mod.io integration, so mod files must be managed manually.
Download the mods you want from the mod.io website using the Download File button
Open the game server installation folder and navigate to the mods folder: <server-install-folder>/CoreKeeperServer_Data/StreamingAssets/Mods/. You may need to create the Mods/ folder if it doesn't already exist.
Unzip each of the mod zips you downloaded inside the folder so that each mod is in its own subfolder.
The name of each mod folder does not matter as long as it is unique, but you probably want it to include the name of the mod for later reference.
Ensure that each mod subfolder has a ModManifest.json file.
Remember to read the general multiplayer notes if you haven't yet. Continue to the next section to help clients get their mods.
The easiest way to ensure that players have exactly the same mods as the server is to use manual mod installation. This means automatic updates don't cause problems with version mismatches.
Set up all of your mods on the server
Zip the server's mods directory
Have all players unsubscribe from every mod in the game's mod.io integration
Send your players the zip file and have them unzip it into their manual mod installation folder.
In general, all players (and the server) should have exactly the same mods installed.
Some mods only need to be installed client side (or server side), refer to the mod's "Application Type" tags, if they exist. If they don't, it's up to the mod developer to tell you this somehow - usually in the description text. If it's not 100% clear, just assume it should be on all sides.
The easiest way to achieve this is to use manual mod installation and for the host to create a zip file of their installed mods and share it with players containing all of the mods they are using.
In cases where mods mismatch, the game will give the error message "Game version mismatch"
If you see this message, make sure your server and client have exactly the same mods and mod versions. Ensure all mods loaded successfully by - sometimes one of the mods fails to load on one side.

How to install mods!
First, how are you playing the game?
The following approaches are available:
The in-game mod integration can be rather finicky, so you may want to try another approach instead. It has the following problems:
Does not show you the list of mod dependencies (mods that must be installed for other mods to function)
Sometimes does not automatically install mod dependencies for you
Poor UX - for example, in order to scroll the screen, you must click and drag the mouse, as the mouse wheel does nothing
If you still want to use this approach, simply launch the game and access the Mods screen from the main menu. To start using a mod, Subscribe to it. The game should automatically check for and install mod updates every launch.
It is highly suggested that you subscribe to each mod dependency individually to ensure it is downloaded correctly. You will have to view the mod on the mod.io website to see what they are.
For the best results, relaunch your game after installing or removing mods.
Core Launcher is a 3rd party tool that makes it easy to manage mods. Check out its page on GitHub for further directions.
Once you have installed it and set it up, create a Profile with the + button to start installing mods.
Core Launcher has a dedicated discussion thread on the Core Keeper discord.
If you'd rather manage mod files manually, you can download them from the mod's mod.io page and place them in the mods folder yourself. Mods installed in this manner will never be automatically updated.
To do this:
Unsubscribe from all mods you are subscribed to on mod.io to prevent conflicts between the two approaches
Open your game installation folder
On a default windows Steam installation, this is:
If that path doesn't work for you, use the above link to find out where that is on your system
Go to the CoreKeeper_Data\StreamingAssets\Mods subfolder, creating any folders along the way if they do not already exist.
On a default windows Steam installation, this is:
Download the mods you want from the mod.io website using the Download File button
Unzip each of the mod zips you downloaded inside the folder so that each mod is in its own subfolder.
The name of each mod folder does not matter as long as it is unique, but you probably want it to include the name of the mod for later reference.
Ensure that each mod subfolder has a ModManifest.json file.
Good to go - launch the game and start playing!
Some mods do not use Core Keeper's modding system to interface with the game and cannot be installed using the means described above. In this case, it is up to the individual mod developer to explain how to install the mod.
