The KLOE experiment, running at the Frascati DAPhiNE phi-factory since 1999, was designed to measure the R(epsilon'/epsilon) ratio to an accuracy of few 10(-4). However, its physics program is wider than CP violation, covering both kaon and non-kaon physics items.During the year 2000 data taking, similar to 20 pb(-1) were collected and a total integrated luminosity of 200 pb(-1) is expected by the end of 2001. A wealth of measurements can be addressed with these data and a number of preliminary results have been already obtained using the year 2000 statistics, in particular on rare K-S decays. After a brief description of the detector, the KS tagging technique is discussed. Preliminary measurements of BR(K-S --> pi(+)pi(-))/BR(K-S --> pi(0)pi(0)) and BR(K-S --> pienu) are then presented. Finally, the perspectives for future analyses are discussed.
