The intention of the CoFH Common Library is to establish a framework for modders to use to avoid “reinventing the wheel,” as it were. This library contains a lot of basic functionality that quite a few mods end up adding at some point during their development.
How to install CoFHLib:
- Download and install Minecraft Forge.
- Download the mod.
- Go to %appdata%.
- Go to .minecraft/mods folder.
- Drag and drop the downloaded jar (zip) file into it.
- If one does not exist you can create one.
- Enjoy the mod.
