QCD-Instantons at HERA -- An Introduction
  We review our ongoing theoretical and phenomenological study of the discovery potential for instanton-induced events in deep-inelastic scattering (DIS) at HERA. Constraints from recent lattice simulations will be exploited and translated into a ``fiducial'' kinematical region for our predictions of the instanton-induced DIS cross-section.
