 #### Arguments
 
-* [`mapStateToProps(state, [ownProps]): stateProps`] \(*Function*): If specified, the component will subscribe to Redux store updates. Any time it updates, `mapStateToProps` will be called. Its result must be a plain object*, and it will be merged into the component’s props. If you omit it, the component will not be subscribed to the Redux store. If `ownProps` is specified as a second argument, its value will be the props passed to your component, and `mapStateToProps` will be additionally re-invoked whenever the component receives new props (e.g. if props received from a parent component have shallowly changed, and you use the ownProps argument, mapStateToProps is re-evaluated).
+* [`mapStateToProps(state, [ownProps]): stateProps`] \(*Function*): If this argument is specified, the new component will subscribe to Redux store updates. This means that any time the store is updated, `mapStateToProps` will be called. The results of `mapStateToProps` must be a plain object*, which will be merged into the component’s props. If you don't want to subscribe to store updates, pass `null` or `undefined` in place of `mapStateToProps`. If `ownProps` is specified as a second argument, its value will be the props passed to your component, and `mapStateToProps` will be additionally re-invoked whenever the component receives new props (e.g. if props received from a parent component have shallowly changed, and you use the ownProps argument, mapStateToProps is re-evaluated).
 
   >Note: in advanced scenarios where you need more control over the rendering performance, `mapStateToProps()` can also return a function. In this case, *that* function will be used as `mapStateToProps()` for a particular component instance. This allows you to do per-instance memoization. You can refer to [#279](https://github.com/reactjs/react-redux/pull/279) and the tests it adds for more details. Most apps never need this.
 
   >The `mapStateToProps` function takes a single argument of the entire Redux store’s state and returns an object to be passed as props. It is often called a **selector**. Use [reselect](https://github.com/reactjs/reselect) to efficiently compose selectors and [compute derived data](http://redux.js.org/docs/recipes/ComputingDerivedData.html).
 
-* [`mapDispatchToProps(dispatch, [ownProps]): dispatchProps`] \(*Object* or *Function*): If an object is passed, each function inside it will be assumed to be a Redux action creator. An object with the same function names, but with every action creator wrapped into a `dispatch` call so they may be invoked directly, will be merged into the component’s props. If a function is passed, it will be given `dispatch`. It’s up to you to return an object that somehow uses `dispatch` to bind action creators in your own way. (Tip: you may use the [`bindActionCreators()`](http://reactjs.github.io/redux/docs/api/bindActionCreators.html) helper from Redux.) If you omit it, the default implementation just injects `dispatch` into your component’s props. If `ownProps` is specified as a second argument, its value will be the props passed to your component, and `mapDispatchToProps` will be re-invoked whenever the component receives new props.
