$|V_{us}|$ and $K_S$ Decays from Kloe

Recent results obtained by the KLOE experiment operating at DA$Φ$NE, the Frascati $ϕ$-factory, are presented. They mainly concern neutral kaon decays including the $K_L$ dominant branching ratios, the $K_L$ lifetime and the extraction of the $CKM$ parameter $V_{us}$ from the $K_L$ semileptonic decays and lifetime. The best world upper limit on $K_S \to \pppo$ channel is also presented
