-List the univeral object in spotlight (ios only).
+List the universal object on Spotlight (iOS only). **Note**: The recommended way to list an item on Spotlight is to use the `automaticallyListOnSpotlight` property with `createBranchUniversalObject` and then call `userCompletedAction(RegisterViewEvent)`, e.g.
+
+```js
+import branch, { RegisterViewEvent } from 'react-native-branch'
+
+let universalObject = branch.createBranchUniversalObject('abc', {
+  automaticallyListOnSpotlight: true,
+  title: 'Item title',
+  contentDescription: 'Item description',
+  contentImageUrl: 'https://example.com/image.png'
+})
+universalObject.userCompletedAction(RegisterViewEvent)
+```

+The `automaticallyListOnSpotlight` property is ignored on Android.

+##### <a id='useractions'></a>[Register User Actions On An Object](#useractions)
+
+We've added a series of custom events that you'll want to start tracking for rich analytics and targeting. Here's a list below with a sample snippet that calls the register view event.
+
+| Event | Description
+| ----- | ---
+| RegisterViewEvent | User viewed the object
+| AddToWishlistEvent | User added the object to their wishlist
+| AddToCartEvent | User added object to cart
+| PurchaseInitiatedEvent | User started to check out
+| PurchasedEvent | User purchased the item
+| ShareInitiatedEvent | User started to share the object
+| ShareCompletedEvent | User completed a share
+
+```js
+import branch, { RegisterViewEvent } from 'react-native-branch'
+let universalObject = branch.createUniversalObject('abc', {})
+universalObject.userCompletedAction(RegisterViewEvent)
+```
+
+Note that `registerView()` is deprecated in favor of `userCompletedAction(RegisterViewEvent)`.
