+# 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.
