-If you don’t use [npm](https://www.npmjs.com), you may grab the latest [UMD](https://npmcdn.com/redux-actions@latest/dist) build from [npmcdn](https://npmcdn.com) (either a [development](https://npmcdn.com/redux-actions@latest/dist/redux-actions.js) or a [production](https://npmcdn.com/redux-actions@latest/dist/redux-actions.min.js) build). The UMD build exports a global called `window.ReduxActions` if you add it to your page via a `<script>` tag. We *don’t* recommend UMD builds for any serious application, as most of the libraries complementary to Redux are only available on [npm](https://www.npmjs.com/search?q=redux).
