To pin down new physics in BSM searches we need a precise knowledge of the physics within the Standard Model. Lattice QCD is able to provide non-perturbative first-principle predictions for the strong interaction such as the mass spectrum for hadrons, decay constants, form factors, and the strong coupling constant alpha_s(M_Z). Uncertainties in any of these predictions directly impact bounds on new physics and must be kept under control. I will give a brief introduction to the ideas behind lattice QCD and try to highlight particular sources of systematic errors before focusing on the continuum extrapolation as one of the central steps to predict continuum physics.
