 Then, we **wrap the components we want to connect to Redux with the `connect()` function from [`react-redux`](http://github.com/gaearon/react-redux)**. Try to only do this for a top-level component, or route handlers. While technically you can `connect()` any component in your app to Redux store, avoid doing this too deeply, because it will make the data flow harder to trace.
 
-**Any component wrapped with `connect()` call will receive a [`dispatch`](../api/Store.md#dispatch) function as a prop, and any state it needs from the global state.** The only argument to `connect()` is a function we call a **selector**. This function takes the global Redux store’s state, and returns the props you need for the component. In the simplest case, you can just return the `state` given to you, but you may also wish to transform it first.

 To make performant memoized transformations with composable selectors, check out [reselect](https://github.com/faassen/reselect). In this example, we won’t use it, but it works great for larger apps.
