Summary of work on SU(3) gauge theory with Nf=3 fundamental quarks. Of course, some unknown investigators have done a very detailed simulation of SU(3) with three light quarks (with odd choices of masses) called "The Universe". We will not cover the enormous amount of work on that simulation and models of it here. We concentrate on work that helps us understand the massless quark theory only.
