-[Rollup](https://github.com/rollup/rollup) plugin to minify generated bundle.
+[Rollup](https://github.com/rollup/rollup) plugin to minify generated bundle. Uses [UglifyJS](https://github.com/mishoo/UglifyJS2) under the hood. There are a few improvements over native uglify:
 
+* uglify is run in worker for every chunk
+* errors are displayed with [babel code frame](https://babeljs.io/docs/en/next/babel-code-frame.html)
+
+_Note: uglify-js is able to transpile only es5 syntax. If you want to transpile es6+ syntax use [terser](https://github.com/TrySound/rollup-plugin-terser) instead_
