-# Implement the 2.1 HAL instead!
-
-It is strongly recommended that you implement the 2.1 HAL directly. See
-`hardware/interfaces/health/2.1/README.md` for more details.
-
-# Implement Health 1.0 HAL
-
-1. Install common binderized service. The binderized service `dlopen()`s
-   passthrough implementations on the device, so there is no need to write
-   your own.
-
-    ```mk
-    # Install default binderized implementation to vendor.
-    PRODUCT_PACKAGES += android.hardware.health@1.0-service
-    ```
-
-1. Add proper VINTF manifest entry to your device manifest. Example:
-
-    ```xml
-    <hal format="hidl">
-        <name>android.hardware.health</name>
-        <transport>hwbinder</transport>
-        <version>1.0</version>
-        <interface>
-            <name>IHealth</name>
-            <instance>default</instance>
-        </interface>
-    </hal>
-    ```
-
-1. Install the proper passthrough implemetation.
-
-    1. If you want to use the default implementation (with default `libhealthd`),
-       add the following to `device.mk`:
-
-        ```mk
-        PRODUCT_PACKAGES += \
-            android.hardware.health@1.0-impl
-        ```
-
-    1. Otherwise, if you have a customized `libhealthd.<board>`:
-
-        1. Define your passthrough implementation. Example (replace `<device>`
-           and `<board>` accordingly):
-
-            ```bp
-            cc_library_shared {
-                name: "android.hardware.health@1.0-impl-<device>",
-                vendor: true,
-                relative_install_path: "hw",
-
-                static_libs: [
-                    "android.hardware.health@1.0-impl-helper",
-                    "android.hardware.health@1.0-convert",
-                    "libhealthd.<board>",
-                ],
-            }
-            ```
-
-        1. Add to `device.mk`.
-
-            ```
-            PRODUCT_PACKAGES += android.hardware.health@1.0-impl-<device>
-            ```
-
-        1. Define appropriate SELinux permissions.
