SND@LHC is a standalone experiment at the Large Hadron Collider (LHC), positioned 480m downstream of IP1 (ATLAS) in the disused service tunnel TI18, that will detect high energy neutrinos produced by heavy flavour quarks in the pseudo-rapidity ($\eta$) region $7.2 <\eta<8.6$. It is a hybrid system, comprising nuclear emulsions and electronic detectors, that enables detecting and distinguishing all three $\nu$ flavours. This allows probing the physics of charm production in the very forward region. The first phase aims at operating the detector throughout LHC Run 3 collecting a total of $150~\rm{fb}^{-1}$. The electronic subdetectors were assembled in the summer, recently operated in test beams and have now been installed in TI18.
