We describe the elastic scattering of weakly interacting dark matter particles from nuclei, with laboratory detection in mind. We focus on the lightest neutralino (a neutral fermion predicted by supersymmetry) as a likely candidate and discuss the physics needed to calculate its elastic scattering cross section and interpret experimental results. Particular emphasis is placed on a proper description of the structure of the proposed detector nuclei. We include a brief discussion of expected count rates in some detectors.
