+- Follow the instructions above for the platform you are building on to prepare the environment.
+- Depending on the target distribution (e.g. `HarmonyOS NEXT` vs pure `OpenHarmony`) the build configuration will differ slightly.
+- Ensure that the following environment variables are set
+  - `DEVECO_SDK_HOME` (Required when targeting `HarmonyOS NEXT`)
+  - `OHOS_BASE_SDK_HOME` (Required when targeting `OpenHarmony`)
+  - `OHOS_SDK_NATIVE` (e.g. `${DEVECO_SDK_HOME}/default/openharmony/native` or `${OHOS_BASE_SDK_HOME}/${API_VERSION}/native`)
+  - `SERVO_OHOS_SIGNING_CONFIG`: Path to json file containing a valid signing configuration for the demo app.
+- Review the detailed instructions at [Building for OpenHarmony].
+- The target distribution can be modified by passing `--flavor=<default|harmonyos>` to `mach <build|package|install>.
