+## Uninstalling thundernetes

+You should first remove all your GameServerBuilds. Since each GameServer has a finalizer, removing the controller before removing GameServer instances will make the GameServer instances get stuck if you try to delete them.

+```bash
+kubectl delete gsb --all -A # this will delete all GameServerBuilds from all namespaces, which in turn will delete all GameServers
+kubectl get gs -A # verify that there are no GameServers in all namespaces
+kubectl delete ns thundernetes-system # delete the namespace with all thundernetes resources
+# delete RBAC resources. You might need to add namespaces for the service account and the role binding
+kubectl delete clusterrole thundernetes-proxy-role thundernetes-metrics-reader thundernetes-manager-role thundernetes-gameserver-editor-role
