-    PRODUCT_PACKAGES += android.hardware.health@2.0-service
-
-   Otherwise, continue to Step 2.
-
-2. Create directory
-   device/<manufacturer>/<device>/health
-
-3. Create device/<manufacturer>/<device>/health/Android.bp
-   (or equivalent device/<manufacturer>/<device>/health/Android.mk)

-}
-
-    3.1 (recommended) To remove healthd from the build, keep "overrides" section.
-    3.2 To keep healthd in the build, remove "overrides" section.
-
-4. Create device/<manufacturer>/<device>/health/android.hardware.health@2.0-service.<device>.rc
-
-service vendor.health-hal-2-0 /vendor/bin/hw/android.hardware.health@2.0-service.<device>
-    class hal
-    user system
-    group system
-    file /dev/kmsg w
-
-5. Create device/<manufacturer>/<device>/health/HealthService.cpp:
-
-#include <health2/service.h>
-int main() { return health_service_main(); }
-
-6. libhealthd dependency:
-
-6.1 If the device has a vendor-specific libhealthd.<soc>, add it to static_libs.
-
-6.2 If the device does not have a vendor-specific libhealthd, add the following
-    lines to HealthService.cpp:
-
-#include <healthd/healthd.h>
-void healthd_board_init(struct healthd_config*) {}
-
-int healthd_board_battery_update(struct android::BatteryProperties*) {
-    // return 0 to log periodic polled battery status to kernel log
-    return 0;
-}
-
-7. Storage related APIs:
-
-7.1 If the device does not implement IHealth.getDiskStats and
-    IHealth.getStorageInfo, add libstoragehealthdefault to static_libs.
-
-7.2 If the device implements one of these two APIs, add and implement the
-    following functions in HealthService.cpp:
-
-void get_storage_info(std::vector<struct StorageInfo>& info) {
-    // ...
-}
-void get_disk_stats(std::vector<struct DiskStats>& stats) {
-    // ...
-}
-
-8. Update necessary SELinux permissions. For example,
-
-# device/<manufacturer>/<device>/sepolicy/vendor/file_contexts
-/vendor/bin/hw/android\.hardware\.health@2\.0-service.<device> u:object_r:hal_health_default_exec:s0
-
-# device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te
-# Add device specific permissions to hal_health_default domain, especially
-# if Step 6.1 or Step 7.2 is done.
-
-9. Implementing health HAL in recovery. The health HAL is used for battery
-status checks during OTA for non-A/B devices. If the health HAL is not
-implemented in recovery, is_battery_ok() will always return true.
-
-9.1 If the device does not have a vendor-specific libhealthd, nothing needs to
-be done. A "backup" implementation is provided in
-android.hardware.health@2.0-impl-default, which is always installed to recovery
-image by default.
-
-9.2 If the device do have a vendor-specific libhealthd, implement the following
-module and include it in PRODUCT_PACKAGES (replace <device> with appropriate
-strings):
-
-// Android.bp
-cc_library_shared {
-    name: "android.hardware.health@2.0-impl-<device>",
-    recovery_available: true,
-    relative_install_path: "hw",
-    static_libs: [
-        "android.hardware.health@2.0-impl",
-        "libhealthd.<device>"
-        // Include the following if Step 7.1, otherwise do Step 7.2
-        "libhealthstoragedefault",

-        "HealthImpl.cpp",
-    ],
-    overrides: [
-        "android.hardware.health@2.0-impl-default",
-    ],
