The identity of dark matter remains unknown despite considerable efforts to find WIMPS at colliders and direct detection experiments. One alternative candidate particle is the sterile neutrino, which forms part of a theory that,in addition to dark matter, can explain neutrino masses and baryogenesis. It would decay into X-rays, and thus constitutes a potential source of the 3.5keV feature reportedly observed in the Galactic Centre, M31 , and clusters of galaxies. It would also behave as warm dark matter, with consequences for the abundance and properties of the Milky Way satellite galaxies. In this talk I will discuss the effect of the sterile neutrino properties on the Milky Way satellites and provide a brief update on the 3.5keV line.
