-CMSGen a fast uniform-like sampler
+CMSGen a fast weighted-like sampler
 ===========================================
 
-This system provides CMSGen, a fast uniform-like sampler. While we give no guarntees that the sampling is uniform, it is currently the best non-guaranteed uniform sampler as per our testing with [Barbarik](https://github.com/meelgroup/barbarik). In case you need guaranteed uniform sampling, please check out [UniGen](https://github.com/meelgroup/unigen). When citing CMSGen, always reference our [FMCAD'21 paper](https://meelgroup.github.io/files/publications/fmcad21_shakuni.pdf) (bibtex [here](https://meelgroup.github.io/publication/fmcad21/cite.bib)).
