 ### Requirements
 
-- The minimum iOS version supported is: `iOS 14`.
+This SDK supports the following Apple platforms:
+- **iOS 14+**
+- **macOS 11+**
+- **watchOS 7+**
+- **tvOS 14+**
 
-Note that this library is intended to be used in a mobile context, and has not been evaluated for use in other type of applications (e.g. server applications, macOS, tvOS, watchOS, etc.).
+The SDK is built with Swift 5.5+ and uses only Foundation and Combine frameworks, making it suitable for all Apple platform contexts including mobile, desktop, wearable, and TV applications.
