Applied Energistics 2, also referred to as AE2, is a mod centered around compact item storage using a digital network called Matter Energy, or ME (Em-Ee).
AE2 has a couple main focus items. These are the ME controller, which is the main component required. The ME Drive, which will take Storage Drives to store items. The ME Terminal, which enables you to store and use items in the ME System. Last but not least is the ME Cable, These can be dyed to any of the 16 colors. They are needed to connect all the above together for the system to work.
Since Applied Energistics 2 has it's own Wiki, the following items will direct to that wiki.
