In the absence of a clear WIMP signal, we should think about alternative candidates for Dark Matter. A very well motivated example is a (up to now hypothetical) sterile neutrino with a mass of a few keV. In this talk, I will give an overview over the topic of keV sterile neutrino Dark Matter, with a particular focus on Dark Matter production in the early Universe and on phenomenological considerations. If time allows, I will also comment on some model building aspects and how to strongly connect sterile neutrinos to the active-neutrino sector. While WIMPs are not dead yet, they have to learn how to live in the neighbourhood of serious competitors.
