+On mobile devices, lists are a core element in many applications. The [`ListView`](/react-native/docs/listview.html#content) component is a special type of [`View`](/react-native/docs/basics-component-view.html) that displays a *vertically* scrolling list of changing, but similarly structured, data.
+
+`ListView` works best for possibly lengthy datasources (e.g., from an endpoint or database), where the number of items may not be known a priori.
+
+> Unlike the more generic [`ScrollView`](/react-native/docs/basics-component-scrollview.html), the `ListView` only renders elements that are currently showing on the screen, not all the elements at once.
 
 The `ListView` component requires two properties, `dataSource` and `renderRow`. `dataSource` is the actual source of information that will be part of the list. `renderRow` takes the data and returns a renderable component to display.

+Given the screen sizes of mobile devices, the ability to scroll through data is generally paramount for a proper usability experience.
+
+The [`ScrollView`](/react-native/docs/scrollview.html) is a generic scrolling container that can host multiple components and views. The scrollable items need not be homogenous, and you can scroll both vertically and horizontally (by setting the `horizontal` property).
+
+`ScrollView` works best to present a list of short, static items of a known quantity. All the elements and views of a `ScrollView` are rendered a priori, even if they are not currently shown on the screen. Contrast this with a `ListView`, which render only those views that are on the screen and remove views that go off-screen.
+
+> [`TextView`](/react-native/docs/basics-component-textview.html) and [`ListView`](/react-native/docs/basics-component-listview.html) are specialized scrollable containers.
+
+This contrived example creates a horizontal `ScrollView` with a static amount of heterogenous elements (images and text).
+
+```JavaScript
+import React, { AppRegistry, ScrollView, Image, Text, View } from 'react-native'
+
+var SimpleScrollView = React.createClass({
+  render(){
+      return(
+        <ScrollView horizontal={true}>
+          <View>
+            <Image source={require('./img/check.png')} />

 Direct text-based user input is a foundation for many apps. Writing a post or comment on a page is a canonical example of this. [`TextInput`](/react-native/docs/textinput.html#content) is a basic component that allows the user to enter text.
