Getting Started with AE2

This AE2 guide was written by neijr in official wiki

Applied Energistics 2 (also known as AE2 or simply AE) is mod that allows people to create storage networks, also known as ME networks (often called AE networks for simplicity).
It also adds means of autocrafting as well as its own kind of storage, item cells (and fluid cells for liquid materials).
