+# GitHub Actions CI/CD Configuration
+
+This document describes how to set up and configure the GitHub Actions CI/CD pipeline for the Sendbird UIKit React Native project.
+
+## Overview
+
+The GitHub Actions workflow handles automated deployment of both iOS and Android sample applications using modern authentication methods and optimized caching strategies.
+
+## Required GitHub Secrets
+
+### Shared
+
+- **SENDBIRD_APP_ID**
+  - Your Sendbird application ID
+  - Used to configure the sample app environment
+
+### Android Deployment
+
+- **FASTLANE_ANDROID_SERVICE_ACCOUNT**
+  - Create service account with Firebase App Distribution role from Google Cloud Console
+  - Download JSON key file
+  - Encode as base64: `cat service-account.json | base64`
+  - Save encoded text to GitHub Secrets
+  - Decoding reference: `echo "encoded-base64-text" | base64 --decode`
+
+- **FASTLANE_ANDROID_APP_ID**
+  - Open your Firebase project settings → General
+  - Find your Android app (formatted like `1:xxxxxxxxxxxxxxxx:android:xxxxx`)
+  - Save app ID to GitHub Secrets
+
+### iOS Deployment
+
+#### App Store Connect API Authentication (Recommended)
+
+- **APP_STORE_CONNECT_API_KEY_ID**
+  - API Key ID from App Store Connect
+  - Format: 10-character alphanumeric string (e.g., `D83848D23B`)
+
+- **APP_STORE_CONNECT_API_ISSUER_ID**
+  - API Key Issuer ID from App Store Connect
+  - Format: UUID (e.g., `227b0bbf-ada8-458c-9d62-3d8022b7d07f`)
+
+- **APP_STORE_CONNECT_API_KEY**
+  - Private key content from the downloaded `.p8` file
+  - Include the full key with headers:
+    ```
+    -----BEGIN PRIVATE KEY-----
+    [Key content]
+    -----END PRIVATE KEY-----
+    ```
+
+#### Certificate Management
+
+- **FASTLANE_IOS_MATCH_GIT_URL**
+  - SSH URL to the private repository storing certificates
+  - Format: `git@github.com:organization/certificates-repo.git`
+  - Must use SSH format for authentication
+
+- **FASTLANE_IOS_MATCH_GIT_PRIVATE_KEY**
+  - SSH private key for accessing the match repository
+  - Generate with: `ssh-keygen -t rsa -b 4096 -C "github-actions@sendbird.com"`
+  - Add the public key to the certificates repository as a deploy key
+  - Save the private key content to GitHub Secrets
+
+- **FASTLANE_IOS_MATCH_PASSWORD**
+  - Password used to encrypt/decrypt certificates in the match repository
+  - Can be found in the match repository
+
+## How to Generate App Store Connect API Key
+
+1. **Login to App Store Connect**
+   - Go to [App Store Connect](https://appstoreconnect.apple.com)
+   - Sign in with your Apple ID
+
+2. **Navigate to API Keys**
+   - Users and Access → Integrations → App Store Connect API
+
+3. **Create New API Key**
+   - Click "Generate API Key"
+   - Set name: `GitHub Actions - Sendbird UIKit`
+   - Select access: `Developer` role
+   - Download the `.p8` file immediately (cannot re-download)
+
+4. **Configure GitHub Secrets**
+   - **Key ID**: Copy from the API key details page
+   - **Issuer ID**: Copy from the API key details page
+   - **Key Content**: Copy entire content of the `.p8` file
+
+## Workflow Features
+
+### Caching Strategy
+- **Node.js Dependencies**: Cached based on `yarn.lock` hash
+- **CocoaPods**: Cached based on `Podfile.lock` hash with validation
+- **Ruby Gems**: Cached automatically by `ruby/setup-ruby` action
+
+### Security
+- **SSH Authentication**: For accessing private certificate repositories
+- **API Key Authentication**: Modern App Store Connect authentication
+- **Secret Validation**: Pre-flight checks for required environment variables
+
+### Platform Support
+- **iOS**: Automatic TestFlight deployment
+- **Android**: Firebase App Distribution deployment
+- **Conditional Execution**: Platform-specific deployment based on input selection
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Pod Cache Validation Failures**
+   - Clear GitHub Actions cache for the repository
+   - Actions → Caches → Delete affected cache entries
+
+2. **SSH Authentication Failures**
+   - Verify the private key format (include headers and footers)
+   - Check if the public key is added to the certificates repository
+
+3. **App Store Connect API Errors**
+   - Verify all three API key components are correctly set
+   - Ensure the API key has sufficient permissions
+   - Check the `.p8` file content format
+
+## Maintenance
+
+- **API Keys**: Renew App Store Connect API keys before expiration (typically 1 year)
+- **Certificates**: Monitor certificate expiration dates in the match repository
+- **SSH Keys**: Rotate SSH keys periodically for security
+- **Dependencies**: Keep fastlane and related tools updated
