 The following example on how to run the background job processor uses [Supervisord](http://supervisord.org), but it is just as possible running it via any other process manager.
 - Copy [supervisor.conf](docs/supervisor.conf) to your supervisord configuration directory, modify it to your needs, and run it.
+- Create an API key for the health checks (optional) and its hash (via `password_encode($password, PASSWORD_DEFAULT)`).
 - Enable background jobs by adding the following settings to your `config.json`:
 
 ```json
 {
-    "backgroundJobs": true
+    "backgroundJobs": {
+        "notifications": true
+    },
+    "healthCheckKey": "$2y$12$...."
 }
