  These lectures from the TASI 2012 summer school outline the basics of
supersymmetry (SUSY) in 3+1 dimensions. Starting from a ground-up development
of superspace, we develop all of the tools necessary to construct SUSY
lagrangians. While aimed at an introductory level, these lectures incorporate a
number of "super-tricks" for SUSY aficionados, including SUSY-covariant
derivatives, equations of motion in superspace, background field methods, and
non-linear realizations of goldstinos.
