+## Property Wrappers
+
+SwiftyRemoteConfig provides property wrappers for Swift 5.1! The property wrapper, `@SwiftyRemoteConfig`, provides an option to use it with key path.
+
+_Note: This propety wrappers only `read` support. You can set new value to the property, but any changes will be reflected to remote config value_ 
+
+### usage
+
+Given keys:
+
+```swift
+extension RemoteConfigKeys {
+    var userColorScheme: RemoteConfigKey<String> { .init("userColorScheme", defaultValue: "default") }
+}
+```
+
+You can declare a Settings struct:
+
+```swift
+struct Settings {
+    @SwiftyRemoteConfig(keyPath: \.userColorScheme)
+    var userColorScheme: String
+}
+```
+
 ## KeyPath dynamicMemberLookup
 
 SwiftyRemoteConfig makes KeyPath dynamicMemberLookpu usable in Swift 5.1.
