The aim of this volume is to provide an introduction to Lattice Quantum Chromodynamics (LQCD) for readers that are non-specialists in the field. In particular, we have in mind advanced undergraduates and graduate students — both theorists and experimentalists — who have a background in nuclear and/or particle physics. This leads to a very limited selection being made from the many topics that are covered by LQCD. The particular topics chosen have, in most cases, analogies in more conventional nuclear and particle physics — good examples being the chapters on the interquark potential and the interactions between hadrons, both of which can be compared with the nucleon-nucleon potential and the interactions between nucleon clusters.
