  The detection of GW170817, it's extensive multi-wavelength follow-up
campaign, and the large amount of theoretical development and interpretation
that followed, have resulted in a significant step forward in the understanding
of the binary neutron star merger phenomenon as a whole. One of its aspects is
seeing the merger as a progenitor of short gamma-ray bursts (SGRB), which will
be the subject of this review. On the one hand, GW170817 observations have
confirmed some theoretical expectations, exemplified by the confirmation that
binary neutron star mergers are the progenitors of SGRBs. In addition, the
multimessenger nature of GW170817 has allowed for gathering of unprecedented
data, such as the trigger time of the merger, the delay with which the
gamma-ray photons were detected, and the brightening afterglow of an off-axis
event. All together, the incomparable richness of the data from GW170817 has
allowed us to paint a fairly detailed picture of at least one SGRB. I will
detail what we learned, what new questions have arisen, and the perspectives
for answering them when a sample of GW170817-comparable events have been
studied.
