The LHCb detector is a single-arm forward spectrometer dedicated to the study of beauty and charm decays. It has been operated successfully up to the end of the Large Hadron Collider (LHC) Run 2 and the collected data led to a series of significant discoveries in the flavour physics field. Flavour observables can probe energy scales well beyond the reach of current and future particle accelerators and are thus of fundamental importance in the quest for New Physics. \\
Since most of the key observables are still statistically limited, upgrades of the LHCb detector have been foreseen to fully exploit the physics reach of the LHC. During the LHC Long Shutdown 2, the LHCb detector underwent a major upgrade, known as Upgrade I, that will allow running at an instantaneous luminosity five times higher than that of the previous running periods. In these proceedings, the key features of the newly installed detector will be discussed at length and a brief perspective about the next foreseen upgrade, known as Upgrade II and expected to be installed before LHC Run 5, will be provided.
