Reactor Experiment for Neutrino Oscillation (RENO) in South Korea observed electron anti-neutrino disappearance using data taken from August 2011 to March 2012 (about 222 live-days) at Yonggwang nuclear reactor site. The observed deficit resulted in measuring the last unknown neutrino mixing angle, , as 0.113 +/- 0.013 (stat) +/- 0.019 (sys.) which is 4.9 sigma level discovery over no oscillation hypothesis. We have taken about 440 live-days of data in total so far and those data are being analyzed. The ultimate goal of RENO analysis is that we would like to reduce statistical and systematic errors down to more than half of what are now by taking data for 3 years in total and by improving analysis method and reducing background. At the end, our future project, RENO-50, is discussed.
