The next-to-minimal supersymmetric standard model (NMSSM) addresses some of the main theoretical and phenomenological issues faced by the minimal supersymmetric model. In doing so, it predicts two additional neutral Higgs bosons and a fifth neutralino. All these particles may have signatures very distinct from those of the MSSM and could thus help establish a non-minimal nature of SUSY. Since the discovery of the SM-like Higgs boson at the LHC, much emphasis has been laid on various versions (and variants) of this model and on probing their signatures at the LHC as well as other experimental facilities. I shall review some of the recent theoretical developments in the NMSSM and the potential of the LHC Run II to unearth some of its specific Higgs and neutralino signatures.
