 BrightFutures
 =============
 
+BrightFutures has reached end-of-life. After a long period of limited development activity, Swift's Async/Await has made the library obsolete. Please consider migrating from BrightFutures to async/await. When you do so, the async `get()` method will prove to be useful:
+
+```swift
+// in an async context...
+
+let userFuture = User.logIn(username, password)
+let user = try await userFuture.get()
+
+// or simply:
+let posts = try await Posts.fetchPosts(user).get()
+```
+
+
+
+The remainder of the README has not been updated recently, but is preserved for historic reasons.

 How do you leverage the power of Swift to write great asynchronous code? BrightFutures is our answer.
 
 BrightFutures implements proven [functional concepts](http://en.wikipedia.org/wiki/Futures_and_promises) in Swift to provide a powerful alternative to completion blocks and support typesafe error handling in asynchronous code.
