+2. `react-native link react-native-camera`
+*To install it with Windows, see manual install below*
 
-Tidelift will coordinate the fix and disclosure.
+### Mostly automatic install with CocoaPods
+1. `npm install react-native-camera --save`
+2. Add the plugin dependency to your Podfile, pointing at the path where NPM installed it:
+```obj-c
+pod 'react-native-camera', path: '../node_modules/react-native-camera'
+```
+3. Run `pod install`
+
+*Note:* You might need to adjust your Podfile following the example below:
+
+```ruby
+target 'yourTargetName' do
+  # See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
+  pod 'React', :path => '../node_modules/react-native', :subspecs => [
+    'Core',
+    'CxxBridge', # Include this for RN >= 0.47
+    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
+    'RCTText',
+    'RCTNetwork',
+    'RCTWebSocket', # Needed for debugging
+    'RCTAnimation', # Needed for FlatList and animations running on native UI thread
+    # Add any other subspecs you want to use in your project
+  ]
+
+  # Explicitly include Yoga if you are using RN >= 0.42.0
+  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
+
+  # Third party deps podspec link
+  pod 'react-native-camera', path: '../node_modules/react-native-camera'
+
+end
+
+post_install do |installer|
+  installer.pods_project.targets.each do |target|
+    if target.name == "React"
+      target.remove_from_project
+    end
+  end
+end
+```
+
+### Manual install
+#### iOS
+1. `npm install react-native-camera --save`
+2. In XCode, in the project navigator, right click `Libraries` ➜ `Add Files to [your project's name]`
+3. Go to `node_modules` ➜ `react-native-camera` and add `RNCamera.xcodeproj`
+4. Expand the `RNCamera.xcodeproj` ➜ `Products` folder
+5. In XCode, in the project navigator, select your project. Add `libRNCamera.a` to your project's `Build Phases` ➜ `Link Binary With Libraries`
+6. Click `RNCamera.xcodeproj` in the project navigator and go the `Build Settings` tab. Make sure 'All' is toggled on (instead of 'Basic'). In the `Search Paths` section, look for `Header Search Paths` and make sure it contains both `$(SRCROOT)/../../react-native/React` and `$(SRCROOT)/../../../React` - mark both as `recursive`.
+
+### Face Detection or Text Recognition Steps
+
+Face Detection/Text Recognition are optional on iOS. If you want them, you are going to need to install Google Mobile Vision frameworks in your project, as mentioned in the next section.
+
+##### No Face Detection steps
+
+If you do not need it and do not want to install the GMV frameworks, open your app xcode project, on the Project Navigator, expand the RNCamera project, right click on the FaceDetector folder and delete it (move to trash, if you want). If you keep that folder and do not follow the GMV installation steps, your project will not compile.
+
+If you want to make this automatic, you can add a postinstall script to your app `package.json`. Inside the `postinstall_project` there is a xcode project ready with the folder removed (we opened xcode, removed the folder from the project and copied the resulting project file). The post install script is:
+```
+#!/bin/bash
+echo "Creating project without FaceDetector"
+if [ -e node_modules/react-native-camera/ios/FaceDetector ] ; then
+  rm -rf node_modules/react-native-camera/ios/FaceDetector
+fi
+cp node_modules/react-native-camera/postinstall_project/projectWithoutFaceDetection.pbxproj node_modules/react-native-camera/ios/RNCamera.xcodeproj/project.pbxproj
+```
+
+And add something like this to the `scripts` section in your `package.json`:
+
+*Note:* The face detection/text recognition code is excluded by default for the **CocoaPods** installation.
+```
+"postinstall": "./scripts/post.sh",
+```
+
+##### Installing GMV frameworks
+GMV (Google Mobile Vision) is used for Face detection/Text recognition by the iOS RNCamera. You have to link the google frameworks to your project to successfully compile the RNCamera project.
+
+###### CocoaPods Path (The only option for Text Recognition)
+
+Modify the dependency towards `react-native-camera` in your
+ `Podfile`, from
+
+ ```
+ pod 'react-native-camera', path: '../node_modules/react-native-camera'
+```
+
+to (for Face Detection)
+
+```
+pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
+  'FaceDetector'
+]
+```
+
+or to (for Text Recognition)
+
+```
+pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
+  'TextDetector'
+]
+```
+*Note:* Text recognition is available only via CocoaPods Path. If you have issues with duplicate symbols you will need to enable dead code stripping option in your Xcode (Target > Build Settings > search for "Dead code stripping") see: https://github.com/firebase/quickstart-ios/issues/487#issuecomment-415313053.
+
+###### Non-CocoaPods Path
+1. Download:
+Google Symbol Utilities: https://www.gstatic.com/cpdc/dbffca986f6337f8-GoogleSymbolUtilities-1.1.1.tar.gz
+
+    Google Utilities: https://dl.google.com/dl/cpdc/978f81964b50a7c0/GoogleUtilities-1.3.2.tar.gz
+
+    Google Mobile Vision: https://dl.google.com/dl/cpdc/df83c97cbca53eaf/GoogleMobileVision-1.1.0.tar.gz
+
+    Google network Utilities: https://dl.google.com/dl/cpdc/54fd7b7ef8fd3edc/GoogleNetworkingUtilities-1.2.2.tar.gz
+
+    Google Interchange Utilities: https://dl.google.com/dl/cpdc/1a7f7ba905b2c029/GoogleInterchangeUtilities-1.2.2.tar.gz
+
+2. Extract everything to one folder. Delete "BarcodeDetector" and "copy" folders from Google Mobile Vision.
+
+3. Open XCode, right click on your project and choose "New Group". Rename the new folder to "Frameworks". Right click on "Frameworks" and select "add files to 'YOUR_PROJECT'". Select all content from the folder of step 2, click on Options. Select "Copy items if needed", leave "Create groups" selected and choose all your targets on the "Add to targets" section. Then, click on "Add".
+
+4. On your target -> Build Phases -> Link Binary with Libraries -> add AddressBook.framework
+5. On your target -> Build Settings -> Other Linker Flags -> add -lz, -ObjC and -lc++
+6. To force indexing and prevent errors, restart xcode and reopen your project again before compiling.
+
+#### Android
+1. `npm install react-native-camera --save`
+2. Open up `android/app/src/main/java/[...]/MainApplication.java`
+  - Add `import org.reactnative.camera.RNCameraPackage;` to the imports at the top of the file
+  - Add `new RNCameraPackage()` to the list returned by the `getPackages()` method. Add a comma to the previous item if there's already something there.
+
+3. Append the following lines to `android/settings.gradle`:
+
+	```gradle
+	include ':react-native-camera'
+	project(':react-native-camera').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-camera/android')
+	```
+
+4. Insert the following lines inside the dependencies block in `android/app/build.gradle`:
+
+	```gradle
+    compile (project(':react-native-camera')) {
+        exclude group: "com.google.android.gms"
+        compile 'com.android.support:exifinterface:25.+'
+        compile ('com.google.android.gms:play-services-vision:12.0.1') {
+            force = true
+        }
+    }
+	```
+
+  > You may need to use different exifinterface versions, e.g. `27.+` instead of `25.+`.
+
+5. Declare the permissions in your Android Manifest (required for `video recording` feature)
+
+  ```java
+  <uses-permission android:name="android.permission.RECORD_AUDIO"/>
+  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
+  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
+  ```
+
+6. Add jitpack to android/build.gradle
+```gradle
+allprojects {
+    repositories {
+        maven { url "https://jitpack.io" }
+        maven { url "https://maven.google.com" }
+    }
+}
+```
+
+The current Android library defaults to the below values for the Google SDK and Libraries,
+
+```gradle
+def DEFAULT_COMPILE_SDK_VERSION             = 26
+def DEFAULT_BUILD_TOOLS_VERSION             = "26.0.2"
+def DEFAULT_TARGET_SDK_VERSION              = 26
+def DEFAULT_GOOGLE_PLAY_SERVICES_VERSION    = "12.0.1"
+def DEFAULT_SUPPORT_LIBRARY_VERSION         = "27.1.0"
+```
+
+You can override this settings by adding a Project-wide gradle configuration properties for
+use by all modules in your ReactNative project by adding the below to `android/build.gradle`
+file,
+
+```gradle
+buildscript {...}
+
+allprojects {...}
+
+/**
+* Project-wide gradle configuration properties for use by all modules
+*/
+ext {
+    compileSdkVersion           = 26
+    targetSdkVersion            = 26

+
+#### Windows
+1. `npm install react-native-camera --save`
+2. Link the library as described here: [react-native-windows / LinkingLibrariesWindows.md](https://github.com/Microsoft/react-native-windows/blob/master/docs/LinkingLibrariesWindows.md)
+For the last step of this guide, you have to add the following things to your `MainReactNativeHost.cs`:
+- in the import section at the very top: `using RNCamera;`
+- in `protected override List<IReactPackage> Packages => new List<IReactPackage>` add a new line with `new RNCameraPackage()`
+3. Add the capabilities (permissions) for the webcam and microphone as described here: [docs.microsoft / audio-video-camera](https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/simple-camera-preview-access#add-capability-declarations-to-the-app-manifest)
+4. Use `RCTCamera` (RNCamera is not supported yet) like described above
+
+Follow the [Q & A](./docs/QA.md) section if you are having compilation issues.
+
+## Usage
+
+### RNCamera
+
+Take a look into this [documentation](./docs/RNCamera.md).
+
+### RCTCamera
+
+Since `1.0.0`, RCTCamera is deprecated, but if you want to use it, you can see its [documentation](./docs/RCTCamera.md).

-## Props
-
----
-
-### `zoom`
-
-This property specifies the zoom value of the camera. Ranges from 0 to 1. Default to 0.
-
-| Type   | Default Value |
-| ------ | ------------- |
-| number | 0             |
-
----
-
-### `maxZoom`
-
-The maximum zoom value of the camera. Defaults to 0.
-
-| Type   | Default Value |
-| ------ | ------------- |
-| number | 0             |
-
----
-
-### `type`
-
-This property defines which camera on the phone the component is using.
-Possible values:
-
-- `front`
-- `back`
-
-| Type   | Default Value |
-| ------ | ------------- |
-| number | 'back'        |
-
----
-
-### `cameraId`
-
-For selecting from multiple cameras on Android devices. See [2492](https://github.com/react-native-community/react-native-camera/pull/2492) for more info. Can be retrieved with `getCameraIds()`
-
-| Type   | Default Value | Platform |
-| ------ | ------------- | -------- |
-| String | `null`        | Android  |
-
----
-
-### `flashMode`
-
-Determines the state of the camera flash. Has the following possible states.
-
-```off: '1',
-on: 'auto',
-auto: 'torch',
-torch: 'off'
-```
-
-| Type   | Default Value |
-| ------ | ------------- |
-| object | `{ off: 1 }`  |
-
-### `ratio`
-
-A string representing the camera ratio in the format 'height:width'. Default is `"4:3"`.
-
-Use `getSupportedRatiosAsync` method to get ratio strings supported by your camera on Android.
-
-| Type   | Default Value |
-| ------ | ------------- |
-| string | `4:3`         |
-
-### `pictureSize`
-
-This prop has a different behaviour for Android and iOS and should rarely be set.
-
-For Android, this prop attempts to control the camera sensor capture resolution, similar to how `ratio` behaves. This is useful for cases where a low resolution image is required, and makes further resizing less intensive on the device's memory. The list of possible values can be requested with `getAvailablePictureSizes`, and the value should be set in the format of `<width>x<height>`. Internally, the native code will attempt to get the best suited resolution for the given `pictureSize` value if the provided value is invalid, and will default to the highest resolution available.
-
-For iOS, this prop controls the internal camera preset value and should rarely be changed. However, this value can be set to setup the sensor to match the video recording's quality in order to prevent flickering. The list of valid values can be gathered from https://developer.apple.com/documentation/avfoundation/avcapturesessionpreset and can also be requested with `getAvailablePictureSizes`.
-
-| Type   | Default Value |
-| ------ | ------------- |
-| string | `None`        |
-
-## Methods

-# AndroidX Migration
-
-AndroidX is the replacement for Google Support Libraries. It is the open-source project that the Android team uses to
-develop, test, package, version and release libraries within Jetpack. Moving forward, all new Android development
-will be in AndroidX, the Support Libraries are depreciated.
-
-> AndroidX is a major improvement to the original Android Support Library. Like the Support Library, AndroidX ships separately from the Android OS and provides backwards-compatibility across Android releases. AndroidX fully replaces the Support Library by providing feature parity and new libraries.
-
-See: https://developer.android.com/jetpack/androidx/
-
-## Migration via Android studio
-
-You can follow the instructions [here](https://developer.android.com/jetpack/androidx/migrate) to migrate you existing
-project.

-        ...
-        minSdkVersion 16
-        targetSdkVersion 28
-    }
-...
-```
-
-If you have any `dependencies {` that are using the old Google Support Libraries, you'll need to update them
-to use the androidx version. Can check the full migration list [here](https://developer.android.com/jetpack/androidx/migrate).

-One way to achieve this (without any additional dependencies ) is using [react-native.ImageEditor.cropImage](https://facebook.github.io/react-native/docs/imageeditor.html#cropimage).

+
+## Properties
+
+#### `aspect`
+
+Values: `Camera.constants.Aspect.fit` or `"fit"`, `Camera.constants.Aspect.fill` or `"fill"` (default), `Camera.constants.Aspect.stretch` or `"stretch"`
+
+The `aspect` property allows you to define how your viewfinder renders the camera's view. For instance, if you have a square viewfinder and you want to fill it entirely, you have two options: `"fill"`, where the aspect ratio of the camera's view is preserved by cropping the view or `"stretch"`, where the aspect ratio is skewed in order to fit the entire image inside the viewfinder. The other option is `"fit"`, which ensures the camera's entire view fits inside your viewfinder without altering the aspect ratio.
+
+#### `cropToPreview`
+
+Values: `true` or `false` (default)
+
+Will crop the captured image to match the content that is displayed in the preview view. Works on both `Android` and `iOS`. Will be ignored if `captureMode` is other then `Camera.constants.CaptureMode.still`.
+
+#### `iOS` `captureAudio`
+
+Values: `true` (Boolean), `false` (default)
+
+_Applies to video capture mode only._ Specifies whether or not audio should be captured with the video.
+
+#### `captureMode`
+
+Values: `Camera.constants.CaptureMode.still` (default), `Camera.constants.CaptureMode.video`
+
+The type of capture that will be performed by the camera - either a still image or video.
+
+#### `captureTarget`
+
+Values: `Camera.constants.CaptureTarget.cameraRoll` (default), `Camera.constants.CaptureTarget.disk`, `Camera.constants.CaptureTarget.temp`, ~~`Camera.constants.CaptureTarget.memory`~~ (deprecated),
+
+This property allows you to specify the target output of the captured image data. The disk output has been shown to improve capture response time, so that is the recommended value. When using the deprecated memory output, the image binary is sent back as a base64-encoded string.
+
+#### `captureQuality`
+
+Values: `Camera.constants.CaptureQuality.high` or `"high"` (default), `Camera.constants.CaptureQuality.medium` or `"medium"`, `Camera.constants.CaptureQuality.low` or `"low"`, `Camera.constants.CaptureQuality.photo` or `"photo"`, `Camera.constants.CaptureQuality["1080p"]` or `"1080p"`, `Camera.constants.CaptureQuality["720p"]` or `"720p"`, `Camera.constants.CaptureQuality["480p"]` or `"480p"`.
+
+This property allows you to specify the quality output of the captured image or video. By default the quality is set to high.
+
+When choosing more-specific quality settings (1080p, 720p, 480p), note that each platform and device supports different valid picture/video sizes, and actual resolution within each of these quality settings might differ. There should not be too much variance (if any) for iOS; 1080p should give 1920x1080, 720p should give 1280x720, and 480p should give 640x480 (note that iOS 480p therefore is NOT the typical 16:9 HD aspect ratio, and the typically-HD camera preview screen may differ greatly in aspect from what you actually record!!). For Android, expect more variance: on most Androids, 1080p _should_ give 1920x1080 and 720p _should_ give 1280x720; however, 480p will at "best" be 853x480 (16:9 HD aspect ratio), but falls back/down to 800x480, 720x480, or "worse", depending on what is closest-but-less-than 853x480 and available on the actual device. If your application requires knowledge of the precise resolution of the output image/video, you might consider manually determine the actual resolution itself after capture has completed (particularly for 480p on Android).
+
+#### `type`
+
+Values: `Camera.constants.Type.front` or `"front"`, `Camera.constants.Type.back` or `"back"` (default)
+
+Use the `type` property to specify which camera to use.
+
+#### `orientation`
+
+Values:
+`Camera.constants.Orientation.auto` or `"auto"` (default),
+`Camera.constants.Orientation.landscapeLeft` or `"landscapeLeft"`, `Camera.constants.Orientation.landscapeRight` or `"landscapeRight"`, `Camera.constants.Orientation.portrait` or `"portrait"`, `Camera.constants.Orientation.portraitUpsideDown` or `"portraitUpsideDown"`
+
+The `orientation` property allows you to specify the current orientation of the phone to ensure the viewfinder is "the right way up."
+
+#### `Android` `playSoundOnCapture`
+
+Values: `true` (default) or `false`
+
+This property allows you to specify whether a shutter sound is played on capture. It is currently android only, pending [a reasonable mute implementation](http://stackoverflow.com/questions/4401232/avfoundation-how-to-turn-off-the-shutter-sound-when-capturestillimageasynchrono) in iOS.
+
+#### `onBarCodeRead`
+
+Will call the specified method when a barcode is detected in the camera's view.
+
+Event contains `data` (the data in the barcode) and `bounds` (the rectangle which outlines the barcode.)
+
+The following barcode types can be recognised:
+
+- `aztec`
+- `code128`
+- `code39`
+- `code39mod43`
+- `code93`
+- `ean13` (`iOS` converts `upca` barcodes to `ean13` by adding a leading 0)
+- `ean8`
+- `pdf417`
+- `qr`
+- `upce`
+- `interleaved2of5` (when available)
+- `itf14` (when available)
+- `datamatrix` (when available)
+
+The barcode type is provided in the `data` object.
+
+#### `barCodeTypes`
+
+An array of barcode types to search for. Defaults to all types listed above. No effect if `onBarCodeRead` is undefined.
+Example: `<Camera barCodeTypes={[Camera.constants.BarCodeType.qr]} />`
+
+#### `flashMode`
+
+Values:
+`Camera.constants.FlashMode.on`,
+`Camera.constants.FlashMode.off`,
+`Camera.constants.FlashMode.auto`
+
+Use the `flashMode` property to specify the camera flash mode.
+
+#### `torchMode`
+
+Values:
+`Camera.constants.TorchMode.on`,
+`Camera.constants.TorchMode.off`,
+`Camera.constants.TorchMode.auto`
+
+Use the `torchMode` property to specify the camera torch mode.
+
+#### `onFocusChanged: Event { nativeEvent: { touchPoint: { x, y } }`
+
+iOS: Called when a touch focus gesture has been made.
+By default, `onFocusChanged` is not defined and tap-to-focus is disabled.
+
+Android: This callback is not yet implemented. However, Android will
+automatically do tap-to-focus if the device supports auto-focus; there is
+currently no way to manage this from javascript.
+
+To get autofocus/tap to focus functionalities working correctly in android
+make sure that the proper permissions are set in your `AndroidManifest.xml`:
+
+```java
+<uses-feature android:name="android.hardware.camera" />
+<uses-feature android:name="android.hardware.camera.autofocus" />
+```
+
+#### `iOS` `defaultOnFocusComponent`
+
+Values:
+`true` (default)
+`false`
+
+If `defaultOnFocusComponent` set to false, default internal implementation of visual feedback for tap-to-focus gesture will be disabled.
+
+#### `iOS` `onZoomChanged: Event { nativeEvent: { velocity, zoomFactor } }`
+
+iOS: Called when focus has changed.
+By default, `onZoomChanged` is not defined and pinch-to-zoom is disabled.
+
+Android: This callback is not yet implemented. However, Android will
+automatically handle pinch-to-zoom; there is currently no way to manage this
+from javascript.
+
+#### `iOS` `keepAwake`
+
+If set to `true`, the device will not sleep while the camera preview is visible. This mimics the behavior of the default camera app, which keeps the device awake while open.
+
+#### `Android` `clearWindowBackground`
+
+Values:
+`true`
+`false` (default)
+
+If you encounter performance issue while using a window background drawable (typically defined in theme to emulate splashscreen behavior), set this to true to automatically clear window background once camera is started.
+
+#### `Android` `permissionDialogTitle`
+
+Starting on android M individual permissions must be granted for certain services, the camera is one of them, you can use this to change the title of the dialog prompt requesting permissions.
+
+#### `Android` `permissionDialogMessage`
+
+Starting on android M individual permissions must be granted for certain services, the camera is one of them, you can use this to change the content of the dialog prompt requesting permissions.
+
+#### `notAuthorizedView`
+
+By default a `Camera not authorized` message will be displayed when access to the camera has been denied, if set displays the passed react element instead of the default one.
+
+#### `pendingAuthorizationView`
+
+By default a <ActivityIndicator> will be displayed while the component is waiting for the user to grant/deny access to the camera, if set displays the passed react element instead of the default one.
+
+#### `pendingAuthorizationView`

+#### `mirrorImage`
+
+If set to `true`, the image returned will be mirrored.
+
+#### `mirrorVideo`
+
+If set to `true`, the video returned will be mirrored.
+
+#### `fixOrientation` (_deprecated_)
+
+If set to `true`, the image returned will be rotated to the _right way up_. WARNING: It uses a significant amount of memory and my cause your application to crash if the device cannot provide enough RAM to perform the rotation.
+
+(_If you find that you need to use this option because your images are incorrectly oriented by default,
+could please submit a PR and include the make model of the device. We believe that it's not
+required functionality any more and would like to remove it._)
+
+## Component instance methods
+
+You can access component methods by adding a `ref` (ie. `ref="camera"`) prop to your `<Camera>` element, then you can use `this.refs.camera.capture(cb)`, etc. inside your component.
+
+#### `capture([options]): Promise`
+
+Captures data from the camera. What is captured is based on the `captureMode` and `captureTarget` props. `captureMode` tells the camera whether you want a still image or video. `captureTarget` allows you to specify how you want the data to be captured and sent back to you. See `captureTarget` under Properties to see the available values.
+
+Supported options:
+
+- `audio` (See `captureAudio` under Properties)
+- `mode` (See `captureMode` under Properties)
+- `target` (See `captureTarget` under Properties)
+- `metadata` This is metadata to be added to the captured image.
+- `metadata.location` This is the object returned from `navigator.geolocation.getCurrentPosition()` (React Native's geolocation polyfill). It will add GPS metadata to the image.
+- `rotation` This will rotate the image by the number of degrees specified.
+- `jpegQuality` (integer between 1 and 100) This property is used to compress the output jpeg file with 100% meaning no jpeg compression will be applied.
+- `totalSeconds` This will limit video length by number of seconds specified. Only works in video capture mode.
+
+The promise will be fulfilled with an object with some of the following properties:
+
+- `data`: Returns a base64-encoded string with the capture data (only returned with the deprecated `Camera.constants.CaptureTarget.memory`)
+- `path`: Returns the path of the captured image or video file on disk
+- `width`: (not yet implemented for Android video) returns the image or video file's frame width (taking image orientation into account)
+- `height`: (not yet implemented for Android video) returns the image or video file's frame height (taking image orientation into account)
+- `duration`: (currently iOS video only) video file duration
+- `size`: (currently iOS video only) video file size (in bytes)
+
+#### `iOS` `getFOV(): Promise`
+
+Returns the camera's current field of view.
+
+#### `hasFlash(): Promise`
+
+Returns whether or not the camera has flash capabilities.
+
+#### `stopCapture()`
+
+Ends the current capture session for video captures. Only applies when the current `captureMode` is `video`.
+
+#### `stopPreview()`
+
+Stops the camera preview from running, and natively will make the current capture session pause.
+
+#### `startPreview()`
+
+Starts the camera preview again if previously stopped.
+
+## Component static methods
+
+#### `iOS` `Camera.checkDeviceAuthorizationStatus(): Promise`
+
+Exposes the native API for checking if the device has authorized access to the camera (camera and microphone permissions). Can be used to call before loading the Camera component to ensure proper UX. The promise will be fulfilled with `true` or `false` depending on whether the device is authorized. Note, [as of iOS 10](https://developer.apple.com/library/content/documentation/AudioVideo/Conceptual/PhotoCaptureGuide/#//apple_ref/doc/uid/TP40017511-CH1-DontLinkElementID_3), you will need to add `NSCameraUsageDescription` and `NSMicrophoneUsageDescription` to your XCode project's Info.plist file or you might experience a crash.
+
+#### `iOS` `Camera.checkVideoAuthorizationStatus(): Promise`
+
+The same as `Camera.checkDeviceAuthorizationStatus()` but only checks the camera permission. Note, as of iOS 10, you will need to add `NSCameraUsageDescription` to your XCode project's Info.plist file or you might experience a crash.
+
+#### `iOS` `Camera.checkAudioAuthorizationStatus(): Promise`
+
+The same as `Camera.checkDeviceAuthorizationStatus()` but only checks the microphone permission. Note, as of iOS 10, you will need to add `NSMicrophoneUsageDescription` to your XCode project's Info.plist file or you might experience a crash.
+
+## Subviews
+
+This component supports subviews, so if you wish to use the camera view as a background or if you want to layout buttons/images/etc. inside the camera then you can do that.
+
+## Example
+
+To see more of the `RCTCamera` in action, you can check out the source in [Example](https://github.com/lwansbrough/react-native-camera/tree/master/Example) folder.
+
+## Open Collective
+
+We are just beginning a funding campaign for react-native-camera. Contributions are greatly appreciated. When we gain more than \$250 we will begin distributing funds to core maintainers in a fully transparent manner. Feedback for this process is welcomed, we will continue to evolve the strategy as we grow and learn more.

-### `pictureSize`
-
-This prop has a different behaviour for Android and iOS and should rarely be set.
-
-For Android, this prop attempts to control the camera sensor capture resolution, similar to how `ratio` behaves. This is useful for cases where a low resolution image is required, and makes further resizing less intensive on the device's memory. The list of possible values can be requested with `getAvailablePictureSizes`, and the value should be set in the format of `<width>x<height>`. Internally, the native code will attempt to get the best suited resolution for the given `pictureSize` value if the provided value is invalid, and will default to the highest resolution available.
-
-For iOS, this prop controls the internal camera preset value and should rarely be changed. However, this value can be set to setup the sensor to match the video recording's quality in order to prevent flickering. The list of valid values can be gathered from https://developer.apple.com/documentation/avfoundation/avcapturesessionpreset and can also be requested with `getAvailablePictureSizes`.

-## Android - other required steps
-
-Add permissions to your app `android/app/src/main/AndroidManifest.xml` file:
-
-```xml
-<!-- Required -->
-<uses-permission android:name="android.permission.CAMERA" />
-
-<!-- Include this only if you are planning to use the camera roll -->

-
-# Additional installation steps
-
-Follow these optional steps if you want to use Face Detection/Text Recognition/BarCode with [MLKit](https://developers.google.com/ml-kit).
-You will need to set-up Firebase project for your app (detailed steps below).
-
-_Note:_ Installing [react-native-firebase](https://github.com/invertase/react-native-firebase) package is NOT necessary.
-
-## iOS
-
-If you want any of these optional features, you will need to use CocoaPods.
-
-### Modifying Podfile
-
-Add dependency towards `react-native-camera` in your `Podfile` with `subspecs` using one of the following:
-
-- For Face Detection:
-
-```ruby
-pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
-  'FaceDetectorMLKit'
-]
-```
-
-- For Text Recognition:
-
-```ruby
-pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
-  'TextDetector'
-]
-```
-
-- For BarCode Recognition:
-
-```ruby
-pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
-  'BarcodeDetectorMLKit'
-]
-```
-
-- For all possible detections:
-
-```ruby
-pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
-  'TextDetector',
-  'FaceDetectorMLKit',
-  'BarcodeDetectorMLKit'
-]
-```
-
-Then run `cd ios && pod install && cd ..`
-
-### Setting up Firebase
-
-Text/Face recognition for iOS uses Firebase MLKit which requires setting up Firebase project for your app.
-If you have not already added Firebase to your app, please follow the steps described in [getting started guide](https://firebase.google.com/docs/ios/setup).
-In short, you would need to
-
-1. Register your app in Firebase console.
-2. Download `GoogleService-Info.plist` and add it to your project
-3. Add `pod 'Firebase/Core'` to your podfile
-4. In your `AppDelegate.m` file add the following lines:
-
-```objective-c
-#import <Firebase.h> // <--- add this
-...
-
-- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
-{
-  [FIRApp configure]; // <--- add this
-  ...
-}
-```

-- If you have issues with duplicate symbols you will need to enable dead code stripping option in your Xcode (Target > Build Settings > search for "Dead code stripping") [see here](https://github.com/firebase/quickstart-ios/issues/487#issuecomment-415313053).
-- If you are using `pod Firebase/Core` with a version set below 5.13 you might want to add `pod 'GoogleAppMeasurement', '~> 5.3.0'` to your podfile
-  </details>
-
-## Android
-
-### Modifying build.gradle
-
-Modify the following lines in `android/app/build.gradle`:
-
-```gradle
-android {
-  ...
-  defaultConfig {
-    ...
-    missingDimensionStrategy 'react-native-camera', 'mlkit' // <--- replace general with mlkit
-  }
-}
-```
-
-### Setting up Firebase
-
-Using Firebase MLKit requires seting up Firebase project for your app. If you have not already added Firebase to your app, please follow the steps described in [getting started guide](https://firebase.google.com/docs/android/setup).
-In short, you would need to
-
-1. Register your app in Firebase console.
-2. Download google-services.json and place it in `android/app/`
-3. Add the folowing to project level `build.gradle`:
-
-```gradle
-buildscript {
-  dependencies {
-  // Add this line
-  classpath 'com.google.gms:google-services:4.0.1' // <--- you might want to use different version
-  }
-}
-```
-
-4. add to the bottom of `android/app/build.gradle` file
-
-```gradle
-apply plugin: 'com.google.gms.google-services'
-```
-
-5. Configure your app to automatically download the ML model to the device after your app is installed from the Play Store. If you do not enable install-time model downloads, the model will be downloaded the first time you run the on-device detector. Requests you make before the download has completed will produce no results.
-
-```xml
-<application ...>
-...
-  <meta-data
-      android:name="com.google.firebase.ml.vision.DEPENDENCIES"
-      android:value="ocr, face" /> <!-- choose models that you will use -->
-</application>
-```
-
-<details>
-  <summary>Additional information in case of problems</summary>

-Version 2.x of react-native-camera moves to using Firebase MLKit for advanced features such as text/face recognition. Users can now opt into useing MLKit in their app by choosing a certain flavor of the library (Android) or selecting a desired podspec (iOS). This allows users who do not need Firebase MLKit-based features to not be forced to set up a Firebase project.
-
-## Required steps
-
-### a. No advanced features/ opt into using deprecated Google Mobile Vision
-
-#### Android
-
-Please insert the following line in `android/app/build.gradle` inside defaultConfig block:
-
-```gradle
-android {
-  ...
-  defaultConfig {
-    ...
-    missingDimensionStrategy 'react-native-camera', 'general' <-- insert this line
-  }
-}
-```
-
-#### iOS
-

-
-3. Configure your app to automatically download the ML model to the device after your app is installed from the Play Store. If you do not enable install-time model downloads, the model will be downloaded the first time you run the on-device detector. Requests you make before the download has completed will produce no results.
