After cloning the repo I wanted to deploy kube-prometheus into my running minikube. I did the steps mentioned in the docu which brought me to the following exception:

namespace "monitoring" created
error: the path "manifests/prometheus-operator" does not exist
Waiting for Operator to register custom resource definitions.................................................................................................................^C

Including a link in dashboard section to the document with all the details (docs/developing-alerts-and-dashboards.md)
