+Methods operate on a ref to the Video element. You can create a ref using code like:
+```
+return (
+  <Video source={...}

+);
+```
+
+#### seek()
+`seek(seconds)`
+
+Seek to the specified position represented by seconds. seconds is a float value.
+
+`seek()` can only be called after the `onLoad` event has fired.
+
+Example:
+```
+this.player.seek(200); // Seek to 3 minutes, 20 seconds
+```
+
+Platforms: all
+
+##### Exact seek
+
+By default iOS seeks within 100 milliseconds of the target position. If you need more accuracy, you can use the seek with tolerance method:
+
+`seek(seconds, tolerance)`
+
+tolerance is the max distance in milliseconds from the seconds position that's allowed. Using a more exact tolerance can cause seeks to take longer. If you want to seek exactly, set tolerance to 0.
+
+Example:
+```
+this.player.seek(120, 50); // Seek to 2 minutes with +/- 50 milliseconds accuracy
+```

+Platforms: iOS

+## Updating
+
+### Version 3.0
+
+#### All platforms now auto-play
+Previously, on Android ExoPlayer if the paused prop was not set, the media would not automatically start playing. The only way it would work was if you set `paused={false}`. This has been changed to automatically play if paused is not set so that the behavior is consistent across platforms.
+
+#### All platforms now keep their paused state when returning from the background
+Previously, on Android MediaPlayer if you setup an AppState event when the app went into the background and set a paused prop so that when you returned to the app the video would be paused it would be ignored.
+
+Note, Windows does not have a concept of an app going into the background, so this doesn't apply there.
+
+#### Use Android SDK 27 by default
+Version 3.0 updates the Android build tools and SDK to version 27. React Native is in the process of [switchting over](https://github.com/facebook/react-native/issues/18095#issuecomment-395596130) to SDK 27 in preparation for Google's requirement that new Android apps [use SDK 26](https://android-developers.googleblog.com/2017/12/improving-app-security-and-performance.html) by August 2018.
+
+You will either need to install the version 27 SDK and version 27.0.3 buildtools or modify your build.gradle file to configure react-native-video to use the same build settings as the rest of your app as described below.
+
+##### Using app build settings
+You will need to create a `project.ext` section in the top-level build.gradle file (not app/build.gradle). Fill in the values from the example below using the values found in your app/build.gradle file.
+```
+// Top-level build file where you can add configuration options common to all sub-projects/modules.
+
+buildscript {
+    ... // Various other settings go here
+}
+
+allprojects {
+    ... // Various other settings go here
+
+    project.ext {
+        compileSdkVersion = 23
+        buildToolsVersion = "23.0.1"
+
+        minSdkVersion = 16
+        targetSdkVersion = 22
+    }
+}
+```
+
 ## TODOS
 
-- [ ] Add support for captions
 - [ ] Add support for playing multiple videos in a sequence (will interfere with current `repeat` implementation)
 - [x] Callback to get buffering progress for remote videos
 - [ ] Bring API closer to HTML5 `<Video>` [reference](http://devdocs.io/html/element/video)
