 If you don’t yet use [npm](http://npmjs.com/) or a modern module bundler, and would rather prefer a single-file [UMD](https://github.com/umdjs/umd) build that makes `ReactRedux` available as a global object, you can grab a pre-built version from [cdnjs](https://cdnjs.com/libraries/react-redux). We *don’t* recommend this approach for any serious application, as most of the libraries complementary to Redux are only available on [npm](http://npmjs.com/).
