  We review the results of arXiv:1208.1481 on orientation reversal and duality
for defects in topological Landau-Ginzburg models, with the intention of
providing an easily accessible toolkit for computations. As an example we
include a proof of the main result on adjunctions in a special case, using
Pauli matrices. We also explain how to compute arbitrary correlators of
defect-decorated planar worldsheets, and briefly discuss the relation to
generalised orbifolds.
