 There are two ways to setup Prometheus integration, depending on where your apps are running:
 * For deployments on Kubernetes, GitLab can [deploy and manage Prometheus](#managed-prometheus-on-kubernetes) in a cluster
-* For other deployment targets, simply [specify the Prometheus server](manual-configuration-of-prometheus).
