CoFH Core is built for players installing Thermal-series or other CoFH mods that depend on it. CoFH Core supplies shared systems and config for Team CoFH's mods, so it is installed as their common dependency. It is approachable enough to drop into a world and use right away, with little setup required.
The mod is available for Forge and NeoForge, so it fits a range of modpacks and launchers. It currently supports Minecraft 1.20.1 and 1.21.1, spanning the 1.20.1 to 1.21.1 releases.

How to install CoFH Core
CoFH Core supports Forge and NeoForge; pick one loader (you cannot mix them) and install it for your chosen Minecraft version. It is built for Minecraft 1.20.1 and 1.21.1, so make sure your profile uses one of those versions.
- 1Choose and install one mod loader from Forge and NeoForge for a Minecraft version this mod supports (1.20.1 and 1.21.1).
- 2Check the download page for any required libraries. CoFH Core lists no hard dependencies here, but it is always worth confirming for your exact version.
- 3Drop the CoFH Core .jar file into your instance's mods folder. On a server, place it in the server's mods folder instead, and make sure every connecting player has it too.
- 4Launch the game with that loader profile and confirm CoFH Core appears in the in-game mods list; if it does not load, re-check the loader, the Minecraft version, and any library requirements.
Supported Minecraft versions: 1.20.1 and 1.21.1. Always download the build that matches your version exactly, as mod files are version-specific.
