Optical/infrared long-baseline interferometry has reached a new stage with the advent of multi-telescope arrays accessible to a broad community of astronomers, most notably VLTI. In preparation for the second generation VLTI instruments, GRAVITY and MATISSE, the VLTI Summer School aims to train astronomers in the best possible exploitation of these instruments over a broad range of science topics.
