 You might need to execute `pod install` in your project's `/ios` folder and set your minimum iOS target to 15.0 in your Podfile (e.g `platform :ios, 15.0`).
 
 * Add project Capabilities as described [iOS quick start](https://developer.transmitsecurity.com/guides/webauthn/quick_start_sdk_ios/)
 * Update YOUR Bundle ID and setup associated domains as described in the [iOS quick start](https://developer.transmitsecurity.com/guides/webauthn/quick_start_sdk_ios/)

 ## Usage
 
-#### Module Setup
+### Module Setup
+
+#### iOS
+1. Open your project's `.xcworkspace` found under `YOUR_PROJECT_PATH/iOS` in Xcode.
+2. Create a plist file named TransmitSecurity.plist in your Application with the following content. CLIENT_ID is configured in your Transmit server. Make sure the file is linked to your target.
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+<plist version="1.0">
+<dict>
+    <key>credentials</key>
+    <dict>
+        <!-- Use api.eu.transmitsecurity.io for EU, api.ca.transmitsecurity.io for CA -->

+        <key>clientId</key>
+        <string>CLIENT_ID</string>
+    </dict>
+</dict>
+</plist>
+```
+#### Android
+1. Open your Android manifest XML file, usually located at `android/app/src/main`.
+2. Update the strings.xml file in your Application with the following content. The CLIENT_ID should be replaced with your client ID
+
+```xml
+<resources>
+    <!-- Transmit Security Credentials -->
+    <string name="transmit_security_app_id">"default_application"</string>
+    <string name="transmit_security_client_id">"CLIENT_ID"</string>

+#### Enhancements
+1. Upgraded native SDKs to iOS `1.1.3` and Android `1.0.19`.
+2. Added initializeSDK API to load configuration from `TransmitSecurity.plist` on iOS, and `strings.xml` on Android.
+3. Added biometrics authentication API.
+4. `uses-sdk:minSdkVersion` Should be equal or greater then `23` to support native biometrics.
+5. Added support for custom domain in SDK initialize API.
