We review the state of the field of terrestrial planet formation with the goal of understanding the formation
of the inner Solar System and low-mass exoplanets. We review the dynamics and timescales of
accretion from planetesimals to planetary embryos and from embryos to terrestrial planets. We discuss
radial mixing and water delivery, planetary spins and the importance of parameters regarding the disk
and embryo propertis. Next we connect accretion models to exoplanets. We first review models for the
growth of hot Super Earths by in situ accretion or inward migration. We show how terrestrial planet formation
is altered in systems with gas giants, in particular by the mechanisms of giant planet migration
and dynamical instabilities. Standard models of terrestrial accretion fail to reproduce the inner Solar
System, and we show how the "Grand Tack" model solves this problem using ideas first developed to
explain the giant exoplanets. Finally, we discuss the key ingredients missing in the current generation of simulations.
