+### Installing the Swift SDK for Android
+
+First install the matching Swift \`${SWIFTLY_NAME}\` toolchain from https://swift.org/download/#releases and add it to your PATH, or by using [swiftly](https://www.swift.org/install/):
+
+\`\`\`
+swiftly install ${SWIFTLY_NAME}
+\`\`\`
+
+Then install the Swift SDK for Android by running the command:
+
+\`\`\`
+swift sdk install https://github.com/${RELEASE_REPO}/releases/download/${SDKNAME}/${ARTIFACTBUNDLE} --checksum ${CHECKSUM}
+\`\`\`
+
+### Installing the Android NDK
+
+The Swift SDK for Android requires the Android Native Development Toolkit ([NDK](https://developer.android.com/ndk/)) to function, which must be installed separately.  Download and unzip the r27c LTS release and set the \`ANDROID_NDK_HOME\` environment variable to the local NDK installation and run the setup script. 
+
+#### macOS configuration command for [android-ndk-r27c-darwin.zip](https://dl.google.com/android/repository/android-ndk-r27c-darwin.zip):
+
+\`\`\`
+ANDROID_NDK_HOME=~/Downloads/android-ndk-r27c ~/Library/org.swift.swiftpm/swift-sdks/${LOCAL_ARTIFACTNAME}/swift-android/scripts/setup-android-sdk.sh
+\`\`\`
+
+#### Linux configuration command for [android-ndk-r27c-linux.zip](https://dl.google.com/android/repository/android-ndk-r27c-linux.zip):
+
+\`\`\`
+ANDROID_NDK_HOME=~/android-ndk-r27c ~/.swiftpm/swift-sdks/${LOCAL_ARTIFACTNAME}/swift-android/scripts/setup-android-sdk.sh
+\`\`\`
+
+#### GitHub Actions:
+
+\`\`\`
+~/.swiftpm/swift-sdks/${LOCAL_ARTIFACTNAME}/swift-android/scripts/setup-android-sdk.sh
+\`\`\`
+
+> [!NOTE]
+> GitHub Actions already includes the Android NDK and defines \`ANDROID_NDK_HOME\`, so there is no need to install the NDK separately. Alternatively, you can use the [swift-android-action](https://github.com/marketplace/actions/swift-android-action) to build Swift packages and run Android tests from a GitHub workflow.
+
+### Building Swift Packages for Android
+
+Now you can compile a Swift package for Android with:
+
+\`\`\`
+$ git clone https://github.com/apple/swift-algorithms.git
+$ cd swift-algorithms/
+$ swiftly run swift build --swift-sdk aarch64-unknown-linux-android28 +${SWIFTLY_NAME}
+\`\`\`
+
+### Running Swift Executables on Android
+
+If you have a connected Android device with [USB debugging enabled](https://developer.android.com/studio/debug/dev-options#Enable-debugging), or are running an [Android emulator](https://developer.android.com/studio/run/emulator), you can create and run a Swift executable with the following commands:
+
+\`\`\`
+$ mkdir ExecutableDemo
+$ cd ExecutableDemo
+$ swift package init --type executable
+$ swiftly run swift build --static-swift-stdlib --swift-sdk aarch64-unknown-linux-android28 +${SWIFTLY_NAME}
+$ adb push .build/debug/ExecutableDemo /data/local/tmp/
+$ adb push \${ANDROID_NDK_HOME}/toolchains/llvm/prebuilt/*/sysroot/usr/lib/aarch64-linux-android/libc++_shared.so /data/local/tmp/
+$ adb shell /data/local/tmp/ExecutableDemo
+\`\`\`

+gh release create --repo ${RELEASE_REPO} --prerelease --notes-file ${NOTES_FILE} --title "${SDKNAME}" "${SDKNAME}" ${ARTIFACTBUNDLE}
