The KLOE experiment, running at the Frascati DAΦNE Φ-factory since 1999, was designed to measure the R(ε'/ε) ratio to an accuracy of few 10{sup}(-4). However, its physics program is wider than CP violation, covering both kaon and non-kaon physics items. During the year 2000 data taking, ～20 pb{sup}(-1) were collected and a total integrated luminosity of 200 pb{sup}(-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{sub}S decays. After a brief description of the detector, the K{sub}S tagging technique is discussed. Preliminary measurements of BR(K{sub}S→π{sup}+π{sup}-)/BR(K{sub}S→π{sup}0π{sup}0) and BR(K{sub}S→πev) are then presented. Finally, the perspectives for future analyses are discussed.
