Simple Google Earth Engine script

I need a simple script to run on Google Earth Engine Code Editor to do the following: - Select Sentinel 2 satelite data (all bands) from 2016/01/01 to 2018/12/31, at 10 m resolution, in 3000 specifc geographical points; -Try to exclude cloudy pixels; - Get the median (from 2016/01/01 to 2018/12/31) for each band at each geographical point. - Export to a CSV table the latitude, longitude and each median band value for each point.
