Installation:

Mekanism requires Minecraft Forge to load. Mekanism is separated into a core module that includes all the primary content, and several other modules that focus on specific aspects of the mod. The core module is required for all the others to be installed, but none of the other modules are dependent upon each other. Just drop the modules you want into your “mods” folder to install, and you’re good to go!

Note: MDK (Mekanism Development Kit) is intended for use by developers and should not be used alongside the other modules.
