The comparison of theory calculations against experimental measurements for many particle collider processes is nowadays one of the main roads towards the discovery of new physics. The tremendous amount of data collected and the great effort of the experimental collaborations have allowed us to reach an unprecedented accuracy in the measurements of many processes. To avoid that the theory uncertainties become the limiting factor of this comparison, a similar effort from the theory community is demanded. In this talk, I will first motivate why matching our best available fixed-order results with parton showers is a necessary step in this direction. Then I will focus on MiNNLOPS, which is one of the latest methods that have been proposed to embed a next-to-next-to-leading order QCD calculation into a full-fledged Monte Carlo event generator. Originally formulated for single boson production, this method has been recently extended to general color-singlet final states and successfully applied to different diboson processes, such as Zγ, W+W− and ZZ. After a brief review of the underlying idea of MiNNLOPS and a presentation of the main results, I will conclude by highlighting the potential of the method for future applications.
