+
+#### Use script
+
+[`sch.sh`](resources/sch.sh) is a script to run service change handler that connects with inventory using HTTPS.  The script attempts to add a custom CA cert to the OS's key store `/etc/ssl/certs/java/cacerts` and then launches service change handler.  The custom CA cert is used to validate the server-side cert provided by inventory at runtime.
+
+The script uses the following environment variables:
+
+Name | Description | Default
+---- | ----------- | -------
+`PATH_TO_CACERT` | Local file path to the CA cert that needs to be added to the keystore | `/opt/cert/cacert.pem`
+`SCH_ARGS` | Args to be passed into the SCH run command | `prod http://consul:8500/v1/kv/service-change-handler?raw=true`
