+---
+
+
+## Requirement
+### Android
+- Java 17 is required for the sample app.
+### iOS
+- Xcode 14.1+    
+Install Apple’s Xcode development software: [Xcode in the Apple App Store](https://apps.apple.com/tw/app/xcode/id497799835?mt=12).
+
+- CocoaPods    
+**CocoaPods** is a dependency manager for iOS projects. [Install CocoaPods by Homebrew](https://formulae.brew.sh/formula/cocoapods). (suggestion)    
+  > Check if Homebrew is installed:
+
+  ```shell
+  $ brew
+  ```
+
+  > How to install Homebrew on MacOS: [Link](https://mac.install.guide/homebrew/3.html)
+
+## Authenticate the npm registry
+
+Create a Personal Access Token (PAT) in your [GitHub setting](https://github.com/settings/tokens). Use the `Configure SSO` button next to your created token to authorize `circlefin` organization. More instructions can be found [here](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens), and check below links for creating GitHub PAT:
+- [Creating a fine-grained personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-fine-grained-personal-access-token)
+- [Creating a personal access token (classic)](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-personal-access-token-classic)
+    
+
+Next, add `.npmrc` file as below:
+```properties
+@circlefin:registry=https://npm.pkg.github.com
+//npm.pkg.github.com/:_authToken=<GITHUB_PAT>
+```
+## Installation
+```shell
+yarn add @circlefin/w3s-pw-react-native-sdk
+```
+### Android
+Add the maven repository to your `android/build.gradle`. It's suggested that load settings from the `local.properties`:
+```properties
+repositories {
+	...
+	maven {
+        	Properties properties = new Properties()
+		// Load local.properties.
+        	properties.load(new File(rootDir.absolutePath + "/local.properties").newDataInputStream())
+
+		url properties.getProperty('pwsdk.maven.url')
+		credentials {
+        		username properties.getProperty('pwsdk.maven.username')
+        		password properties.getProperty('pwsdk.maven.password')
+		}
+	}
+}
+```
+Add the maven setting values in the `local.properties` file.
+```properties
+pwsdk.maven.url=https://maven.pkg.github.com/circlefin/w3s-android-sdk
+pwsdk.maven.username=<GITHUB_USERNAME>
+pwsdk.maven.password=<GITHUB_PAT>
+```
+> **Note**
+> When pasting the values above for `<GITHUB_USERNAME>` and `<GITHUB_PAT>`, make sure to not surround the values with quotes.
+### iOS
+Run the command under `ios/`:
+```
+pod install
+```
+## New Architecture Support
+The SDK is supporting both React Native old and [new architectures](https://reactnative.dev/docs/the-new-architecture/landing-page).
+You can enable or disable the new architecture by changing the project setting.
+### Android
+Set the `android/gradle.properties` file as below to enable new architecture or false to disable. 
+```properties
+newArchEnabled=true
+```
+### iOS
+Reinstall your pods by running pod install with the right flag:
+```shell
+bundle install && RCT_NEW_ARCH_ENABLED=1 bundle exec pod install
+```
+Or run without flag to use old architecture:
+```sh
+pod install
+```
+## Run the Sample App
+1. Edit `src/config.json` ➜ `pw_app_id` to fill in your `APP ID`.
+2. (Optional) Open the project in [Android Studio](https://developer.android.com/studio) and see if there's any build error.
+    - File ➜ Open ➜ choose `android` folder.
+    - File ➜ Sync Project with Files.
+    - Build ➜ Rebuild Project.
+3. (Optional) Open the project in [Xcode](https://apps.apple.com/tw/app/xcode/id497799835?mt=12) and build to see if there's any build error.
+    - Open `W3sSampleWallet.xcworkspace` in Xcode.
+    - Product ➜ Build.
+4. Run on device  
+    You can simply run the command below or find more detail on [reactnative.dev](https://reactnative.dev/docs/running-on-device?package-manager=yarn&platform=android).
+      - Android
+        ```sh
+        yarn android
+        ```
+      - iOS
+        ```sh
