  Mapping millimetre continuum emission has become a key issue in modern
multi-wavelength astrophysics. In particular, spectrum-imaging at low frequency
resolution is an asset for characterizing the clusters of galaxies via the
Sunyaev Zeldovich (SZ) effect. In this context, we have built a ground-based
spectrum-imager named KIDs Interferometer Spectrum Survey (KISS). This
instrument is based on two 316-pixel arrays of Kinetic Inductance Detectors
(KID) cooled to 150 mK by a custom dilution refrigerator-based cryostat. By
using Ti-Al and Al absorbers, we can cover a wide frequency range between 80
and 300 GHz. In order to preserve a large instantaneous Field of View (FoV) 1
degree the spectrometer is based on a Fourier Transform interferometer. This
represents a technological challenge due to the fast scanning speed that is
needed to overcome the effects of background atmospheric fluctuations. KISS is
installed at the QUIJOTE 2.25 m telescope in Tenerife since February 2019 and
is currently in its commissioning phase. In this proceeding we present an
overview of the instrument and the latest results.
