-You can define which actions your list should support through the `onMoveAction` and `onDeleteAction` initializer parameters.
-**Per default the move and delete functions are disabled if you skip the parameters.**
+To enable the move or delete function just use the related `onMove` or `onDelete` view modifier.
+**Per default the functions are disabled if you don't add the view modifiers.**

+## Migration 3.0 -> 4.0
+
+Thanks to a hint from @SpectralDragon I could refactor the `onMove` and `onDelete` functionality to view modifiers.
+
+**Before:**
+```swift
+import AdvancedList
+
+@State private var listState: ListState = .items
+
+AdvancedList(yourData, content: { item in
+    Text("Item")
+}, listState: $listState, onMoveAction: { (indexSet, index) in
+    // move me
+}, onDeleteAction: { indexSet in
+    // delete me
+}, emptyStateView: {
+    Text("No data")
+}, errorStateView: { error in
+    VStack {
+        Text(error.localizedDescription)
+            .lineLimit(nil)
+        
+        Button(action: {
+            // do something
+        }) {
+            Text("Retry")
+        }
+    }
+}, loadingStateView: {
+    Text("Loading ...")
+}, pagination: .noPagination)
+```
+
+**After:**
+```swift
+import AdvancedList
+
+@State private var listState: ListState = .items
+
+AdvancedList(yourData, content: { item in
+    Text("Item")
+}, listState: $listState, emptyStateView: {
+    Text("No data")
+}, errorStateView: { error in
+    VStack {
+        Text(error.localizedDescription)
+            .lineLimit(nil)
+        
+        Button(action: {
+            // do something
+        }) {
+            Text("Retry")

+    }
+}, loadingStateView: {
+    Text("Loading ...")
+}, pagination: .noPagination)
+.onMove { (indexSet, index) in
+    // move me
+}
+.onDelete { indexSet in
+    // delete me
