 ## Transferable
 
 ``Timecode`` conforms to the [`Transferable`](https://developer.apple.com/documentation/coretransferable/transferable) protocol which allows instances to be dragged & dropped or copied to/from the clipboard using declarative SwiftUI syntax.

+## Pasted Timecode Validation Against Local Context
+
+When accepting timecode pasted from the clipboard, it is common to validate it against a local context.
+
+For example, you may want to constrain pasted timecode to a certain frame rate, subframes base and upper limit.
+
+`TimecodeKitUI` offers static API to perform this validation by supplying policies to validate against.
+
+```swift
+@TimecodeState private var timecode: Timecode
+
+// pass in the `Timecode` instance received from the pasteboard
+// from the `pasteDestination()` or `onPasteCommand()` view modifiers:
+func validate(pastedTimecode: Timecode) {
+    guard let newTimecode = TimecodeField.validate(
+        pastedTimecode: pastedTimecode,
+        localTimecodeProperties: timecode.properties,
+        pastePolicy: .preserveLocalProperties,
+        validationPolicy: .enforceValid
+    ) else { return }
+
+    timecode = newTimecode
+}
+```
+
+> Note:
+>
+> This method is offered on `TimecodeField` since it is the same API the field uses internally when handling its own paste events.
+> 
+> Because `TimecodeField` implements copy and paste functionality under the hood, calling the `validate` method is unnecessary as it is already being called internally on user paste events.
+>
+> Instead, use the corresponding view modifiers to specify the policies on your `TimecodeField` instance:
+>
+> - `timecodeFieldPastePolicy(_:)`
+> - `timecodeFieldValidationPolicy(_:)`
+> - `timecodeFieldInputStyle(_:)`
+> 
+> See `TimecodeField` documentation in the `TimecodeKitUI` module for more information, or try out the **Timecode UI** example project located in the **Examples** folder within this repo.
