 You can require only needed modules, like in examples in examples at the top of `README.md`. Available entry points for methods / constructors and namespaces: for example, `core-js/es/array` (`core-js-pure/es/array`) contains all [ES `Array` features](#ecmascript-array), `core-js/es` (`core-js-pure/es`) contains all ES features.

+Modular standard library for JavaScript. Includes polyfills for [ECMAScript 5, 2015, 2016, 2017](https://github.com/zloirock/core-js#ecmascript): [promises](https://github.com/zloirock/core-js#ecmascript-promise), [symbols](https://github.com/zloirock/core-js#ecmascript-symbol), [collections](https://github.com/zloirock/core-js#ecmascript-collections), iterators, [typed arrays](https://github.com/zloirock/core-js#ecmascript-typed-arrays), many other features, [ECMAScript proposals](https://github.com/zloirock/core-js#ecmascript-proposals), [some cross-platform WHATWG / W3C ECMAScript-related features and proposals](https://github.com/zloirock/core-js#web-standards) like [setImmediate](https://github.com/zloirock/core-js#setimmediate). You can load only required features or use it without global namespace pollution.
+
+[*Example*](http://goo.gl/a2xexl):
+```js
+import 'core-js'; // <- at the top of your entry point
+
+Array.from(new Set([1, 2, 3, 2, 1]));          // => [1, 2, 3]
+[1, [2, 3], [4, [5]]].flatten(2);              // => [1, 2, 3, 4, 5]
+Promise.resolve(32).then(x => console.log(x)); // => 32
+```
+
+*You can load only required features*:
+```js
+import 'core-js/features/array/from';    // <- at the top of your entry point
+import 'core-js/features/array/flatten'; // <- at the top of your entry point
+import 'core-js/features/set';           // <- at the top of your entry point
+import 'core-js/features/promise';       // <- at the top of your entry point
+
+Array.from(new Set([1, 2, 3, 2, 1]));          // => [1, 2, 3]
+[1, [2, 3], [4, [5]]].flatten(2);              // => [1, 2, 3, 4, 5]
+Promise.resolve(32).then(x => console.log(x)); // => 32
+```
+
+*Or use it without global namespace pollution*:
+```js
+import from from 'core-js-pure/features/array/from';
+import flatten from 'core-js-pure/features/array/flatten';
+import Set from 'core-js-pure/features/set';
+import Promise from 'core-js-pure/features/promise';
+

+Promise.resolve(32).then(x => console.log(x)); // => 32
+```
