 This action can be run on any of the GitHub `ubuntu-*` and `macos-*` [runner images](https://github.com/actions/runner-images). However, due to the inability of macOS on ARM to run nested virtualization ([issue](https://github.com/ReactiveCircus/android-emulator-runner/issues/350)), the Android emulator cannot be run on these platforms, and so running on any macOS image that uses ARM (including `macos-14` and `macos-15`) requires disabling tests with `run-tests: false`. Running tests are supported on `macos-13`, as well as the large Intel macOS images like `macos-14-large` and `macos-15-large`.
 
+An example of disabling running tests on ARM macOS images is:
+
+```yml
+jobs:
+  macos-android:
+    runs-on: macos-15
+    steps:
+      - uses: actions/checkout@v4
+      - name: "Test Swift Package on macOS"
+        run: swift test
+      - name: "Test Swift Package on Android"
+        uses: skiptools/swift-android-action@v2
+        with:
+          run-tests: false
+```
