   The Runners do not need to be installed in the Kubernetes cluster, but the
   Kubernetes executor is easy to use and is automatically autoscaling.
   Docker-based Runners can be configured to autoscale as well, using [Docker

+- **Prometheus** (for Auto Monitoring)
+
+  To enable Auto Monitoring, you
   will need Prometheus installed somewhere (inside or outside your cluster) and
   configured to scrape your Kubernetes cluster. To get response metrics
   (in addition to system metrics), you need to
   [configure Prometheus to monitor NGINX](../../user/project/integrations/prometheus_library/nginx_ingress.md#configuring-nginx-ingress-monitoring).

   The [Prometheus service](../../user/project/integrations/prometheus.md)
   integration needs to be enabled for the project, or enabled as a
   [default service template](../../user/project/integrations/services_templates.md)
