+`ASScrollNode` is literally a wrapped `UIScrollView`.
+
+### Basic Usage
+
+In case you're not familiar with scroll views, they are basically windows into content that would take up more space than can fit in that area.
+
+Say you have a giant image, but you only want to take up 200x200 pts on the screen.
+
+<div class = "highlight-group">
+<span class="language-toggle"><a data-lang="swift" class="swiftButton">Swift</a><a data-lang="objective-c" class = "active objcButton">Objective-C</a></span>
+
+<div class = "code">
+<pre lang="objc" class="objcCode">
+UIImage *scrollNodeImage = [UIImage imageNamed:@"image"];
+ASScrollNode *scrollNode = [[ASScrollNode alloc] init];
+
+scrollNode.preferredFrameSize = CGSizeMake(200.0, 200.0);
+
+UIScrollView *scrollNodeView = scrollNode.view;
+[scrollNodeView addSubview:[[UIImageView alloc] initWithImage:scrollNodeImage]];
+scrollNodeView.contentSize = scrollNodeImage.size;
+</pre>
+<pre lang="swift" class = "swiftCode hidden">
+let scrollNodeImage = UIImage(named: "image")
+let scrollNode = ASScrollNode()
+
+scrollNode.preferredFrameSize = CGSize(width: 200.0, height: 200.0)
+
+let scrollNodeView = scrollNode.view
+scrollNodeView.addSubview(UIImageView(image: scrollNodeImage))
+scrollNodeView.contentSize = scrollNodeImage.size
+</pre>
+</div>
+</div>
+
+As you can see, the scrollNode's underlying view is a `UIScrollView`.
