 Redux is a valuable tool for organizing your state, but you should also consider whether it's appropriate for your situation.  Don't use Redux just because someone said you should - take some time to understand the potential benefits and tradeoffs of using it.

+Here are some suggestions on when it makes sense to use Redux:
 * You have reasonable amounts of data changing over time
 * You need a single source of truth for your state
 * You find that keeping all your state in a top-level component is no longer sufficient

 ## Developer Experience
 
-Dan Abramov (author of Redux) wrote Redux while working on his React Europe talk called [“Hot Reloading with Time Travel”](https://www.youtube.com/watch?v=xsSnOQynTHs). His goal was to create a state management library with minimal API but completely predictable behavior, so it is possible to implement logging, hot reloading, time travel, universal apps, record and replay, without any buy-in from the developer.

 ## Influences
 
 Redux evolves the ideas of [Flux](http://facebook.github.io/flux/), but avoids its complexity by taking cues from [Elm](https://github.com/evancz/elm-architecture-tutorial/).

 If you're not, you can [access these files on unpkg](https://unpkg.com/redux/), download them, or point your package manager to them.
 
-Most commonly people consume Redux as a collection of [CommonJS](http://webpack.github.io/docs/commonjs.html) modules. These modules are what you get when you import `redux` in a [Webpack](https://webpack.js.org/), [Browserify](http://browserify.org/), or a Node environment. If you like to live on the edge and use [Rollup](http://rollupjs.org), we support that as well.

 If you don't use a module bundler, it's also fine. The `redux` npm package includes precompiled production and development [UMD](https://github.com/umdjs/umd) builds in the [`dist` folder](https://unpkg.com/redux/dist/). They can be used directly without a bundler and are thus compatible with many popular JavaScript module loaders and environments. For example, you can drop a UMD build as a [`<script>` tag](https://unpkg.com/redux/dist/redux.js) on the page, or [tell Bower to install it](https://github.com/reactjs/redux/pull/1181#issuecomment-167361975). The UMD builds make Redux available as a `window.Redux` global variable.
