 The NPM package distributed in npmjs.com includes both ES2015+ and ES5 files:
 
-* `dist/` is compiled into ES2015+, provided for NodeJS v10 or later
-* `dist.es5+umd/` is compiled into ES5 with UMD-style single file
-  * `dist.es5+umd/msgpack.min.js` - the default, minified file (UMD)
-  * `dist.es5+umd/msgpack.js` - an optional, non-minified file (UMD)
-* `dist.es5+esm/` is compiled into ES5 and placed as ES modules, provided for webpack-like bundlers, not NodeJS
+* `dist/` is compiled into ES2019 with CommomJS, provided for NodeJS v10
+* `dist.es5+umd/` is compiled into ES5 with UMD
+  * `dist.es5+umd/msgpack.min.js` - the minified file
+  * `dist.es5+umd/msgpack.js` - the non-minified file
+* `dist.es5+esm/` is compiled into ES5 with ES modules, provided for webpack-like bundlers and NodeJS's ESM-mode
 
 If you use NodeJS and/or webpack, their module resolvers use the suitable one automatically.
