 ### Polyfills
 
-Uppy heavily uses Promises. If your target environment [does not support Promises](https://caniuse.com/#feat=promises), use a polyfill like `es6-promise` before initialising Uppy.
+Uppy heavily uses Promises. If your target environment [does not support Promises](https://caniuse.com/#feat=promises), use a polyfill like `core-js` before initialising Uppy.
 
 When using remote providers like Google Drive or Dropbox, the Fetch API is used. If your target environment does not support the [Fetch API](https://caniuse.com/#feat=fetch), use a polyfill like `whatwg-fetch` before initialising Uppy. The Fetch API polyfill must be loaded _after_ the Promises polyfill, because Fetch uses Promises.
 
 With a module bundler, you can use the required polyfills like so:
 
 ```shell
-npm install es6-promise whatwg-fetch abortcontroller-polyfill math-log2 md-gum-polyfill resize-observer-polyfill symbol-es6 url-polyfill
+npm install core-js whatwg-fetch abortcontroller-polyfill md-gum-polyfill resize-observer-polyfill
