In this talk, I will briefly discuss our current understanding of the first NS-NS merger event, GRB 170817A, coincidently detected by both the LIGO-Virgo gravitational wave detectors, including its event rates, ejecta topology, radiation mechanism and what can learn from the 1.7 s time delay between the GRB and the gravitational signal.
