  I attempt to summarize our knowledge of planet formation in evolving
protoplanetary discs. I first review the physics of disc evolution and
dispersal. For most of the disc lifetime evolution is driven by accretion and
photoevaporation, and I discuss how the interplay between these processes
shapes protoplanetary discs. I also discuss the observations that we use to
test these models, and the major uncertainties that remain. I will then move on
to consider planet formation and migration in evolving discs, and discuss how
observations of both discs and planets can be used to inform our understanding
of protoplanetary disc evolution.
