  This is a written account of the computer tutorial offered at the Sixth
MC4BSM workshop at Cornell University, March 22-24, 2012. The tools covered
during the tutorial include: FeynRules, LanHEP, MadGraph, CalcHEP, Pythia 8,
Herwig++, and Sherpa. In the tutorial, we specify a simple extension of the
Standard Model, at the level of a Lagrangian. The software tools are then used
to automatically generate a set of Feynman rules, compute the invariant matrix
element for a sample process, and generate both parton-level and fully
hadronized/showered Monte Carlo event samples. The tutorial is designed to be
self-paced, and detailed instructions for all steps are included in this
write-up. Installation instructions for each tool on a variety of popular
platforms are also provided.
