+1. Scroller
+    ```swift
+    Scroller(.vertical, value: $valueV) {
+        ForEach(0...5, id: \.self) { index in
+            GeometryReader { proxy in
+                ScrollerVContent(value: proxy.scrollerValue(.vertical))
+            }
+        }
+    } lastContent: {
+        Rectangle()
+            .fill(Color.blue)
+            .overlay(Text("LastView"))
+            .foregroundColor(Color.white)
+    }
+    ```
+
+        
+3. Each view only needs to conform to the ScrollerContent protocol.
+    ```swift
+    struct ScrollerVContent: ScrollerContent {
+    
+        /// Bind each view's scroll-relative value. It is a value between 0 and 1.
+        var value: CGFloat = 0
+        
+        var body: some View {
+            GeometryReader { proxy in
+                ScrollerInfoView(axes: .vertical, value: value, proxy: proxy)
+                    .offset(y: proxy.size.height * value)
+                    .padding(10)
+                Rectangle().fill(Color.blue)
+                    .frame(width: proxy.size.width * value, height: 5)
+                    .offset(y: proxy.size.height * value)
+            }
+            .background(Color.orange.opacity(1.0 - value))
+        }
