+## Troubleshooting walkthrough
+
+Most Kubernetes troubleshooting can be broken down into 2 categories:
+
+- [Troubleshooting helm](#troubleshooting-helm)
+- [Troubleshooting Kubernetes integration](#troubleshooting-kubernetes-integration)
+
+Generally speaking, if it does not fall into those two categories, it is either:
+
+- Something GitLab support needs to look into.
+- Something a Kubernetes administrator needs to look into.
+
+Exercise caution. Issues that appear to be GitLab problems can be Kubernetes or
+infrastructure issues.

+Setting up Kubernetes can be tricky and costly.
+
+The easiest method is to spin up a minikube instance locally. If you are
+wanting to troubleshoot the Kubernetes integration, you would also want to spin
+up a local GitLab install (docker usually works best for this).
+
+You can read more using minkube via
+[Kubernetes documentation](https://kubernetes.io/docs/setup/learning-environment/minikube/).
