Two basic motivations for an upgraded JLab facility arc the needs to determine the essential nature of light-quark confinement and dynamical chiral symmetry breaking (DCSB); and to understand nucleon structure and spectroscopy in terms of QCD's elementary degrees of freedom During the next, toll year's a programme of experiment and theory will be conducted that call address these questions. We present a Dyson-Schwinger equation perspective on this effort with numerous illustrations; amongst them. an interpretation of string-breaking, a symmetry-preserving truncation for mesons, the nucleon's strangeness sigma-term, and the neutron's charge distribution
