-`Store.binding(get:tag:animation:)` lets you create a [binding](https://developer.apple.com/documentation/swiftui/binding) that represents some part of the state. A get function reads the state into a value, a tag function turns a value set on the binding into an action. The result is a binding that can be passed to any vanilla SwiftUI view, yet changes state only through deterministic updates.

-Alternatively, you can use the lower-level `Update.transaction` API to set the [Transaction](https://developer.apple.com/documentation/swiftui/transaction) for this state update:
-
-```swift
-func update(
-    state: State,
-    environment: Environment,
-    action: Action
-) -> Update<State, Action> {
-    switch action {

+When you specify a transition or animation as part of an Update thisway, Store will use it when setting the state for the update.
