+
+RxKeyboard provides a reactive way of keyboard handling. Forget about `UIKeyboardWillShow` and `UIKeyboardWillHide`. It also perfectly works with `UIScrollViewKeyboardDismissMode.interactive`.

+
+## At a Glance
+
+Observing keyboard frame:
+
+```swift
+RxKeyboard.instance.frame
+  .drive(onNext: { frame in
+    print(frame)
+  })
+  .addDisposableTo(disposeBag)
+```
+
+Observing keyboard visible height:
+
+```swift
+RxKeyboard.instance.visibleHeight
+  .drive(onNext: { keyboardVisibleHeight in
+    toolbarBottomConstraint.constant = -1 * keyboardVisibleHeight
+  })
+  .addDisposableTo(disposeBag)
+```
+    
+> **Note**: In real world, you should use `setNeedsLayout` and `layoutIfNeeded`. See the [demo project](https://github.com/devxoul/RxKeyboard/blob/master/Demo/Sources/ViewControllers/ViewController.swift#L62-L70) for example.
