+# GitHub Actions Workflows
+
+This directory contains GitHub Actions workflows for continuous integration and deployment.
+
+## Active Workflows
+
+### Android Build (`android-build.yml`)
+
+Automatically builds and tests the Android library on pull requests.
+
+**Triggers:**
+- Pull request opened, synchronized, or reopened
+- Only runs when relevant files change (android/, src/, package.json)
+
+**What it does:**
+1. Sets up Java 17 and Node.js 18
+2. Installs npm dependencies
+3. Validates Gradle wrapper
+4. Builds the Android library using Gradle
+5. Uploads build reports on failure
+
+### iOS Build (`ios-build.yml`)
+
+Automatically builds and tests the iOS library on pull requests.
+
+**Triggers:**
+- Pull request opened, synchronized, or reopened
+- Only runs when relevant files change (ios/, src/, package.json, podspec)
+
+**What it does:**
+1. Sets up Node.js 18 and Ruby 3.0
+2. Installs npm dependencies
+3. Installs CocoaPods
+4. Validates the podspec
+5. Builds the iOS library using xcodebuild
+6. Uploads build logs on failure
+
+### Other Workflows
+
+#### Test and Build (`test-and-build.yml`)
+
+Manual workflow for comprehensive testing across all environments.
+
+**Triggers:**
+- Manual dispatch only (`workflow_dispatch`)
+
+**What it does:**
+1. Runs JavaScript tests
+2. Builds the TypeScript library
+3. Builds Android with Gradle
+4. Sets up iOS environment (build steps incomplete)
+
+#### Documentation and Release
+
+- `publish-documentation.yml` - Publishes documentation to GitHub Pages
+- `release-and-publish-npm.yml` - Handles releases and npm publishing
+
+## Running Workflows Locally
+
+### Android Build
+
+```bash
+cd android
+./gradlew build
+```
+
+### iOS Build
+
+```bash
+cd ios
+xcodebuild clean build \
+  -project RNBluetoothClassic.xcodeproj \
+  -scheme RNBluetoothClassic \
+  -sdk iphonesimulator \
+  -configuration Release
+```
+
+### JavaScript/TypeScript
+
+```bash
+npm ci
+npm run test
+npm run build
+```
+
+## Notes
+
+- The Android and iOS workflows use path filters to only run when relevant code changes
+- Build artifacts and logs are uploaded on failure for debugging
+- The workflows use the latest stable versions of actions and tools

+### Continuous Integration
+
+The project uses GitHub Actions for continuous integration. When you open a pull request:
+
+- **Android Build**: Automatically compiles the Android library to ensure your changes don't break the build
+- **iOS Build**: Automatically compiles the iOS library to ensure your changes don't break the build
+
+These workflows run automatically when you modify relevant files (android/, ios/, or src/ directories). See [.github/workflows/README.md](.github/workflows/README.md) for more details.

 #### Android
 
 When first building the Android project there were issues with react-native-create-library and the version of Android/Gradle installed on my machine.  This needed to be resolved by ensuring that the project was inline with the version of Android Studio and the Android plugin for gradle.  In my case, the project was configured with 1.3.1 and 2.2, which caused problems, in order to resolve [Android plugin for gradle versions](https://developer.android.com/studio/releases/gradle-plugin.html)
