 Jsonnet is a turing complete language, any logic can be reflected in it. It also has powerful merge functionalities, allowing sophisticated customizations of any kind simply by merging it into the object the library provides.
 
+### Cluster Creation Tools
+
 A common example is that not all Kubernetes clusters are created exactly the same way, meaning the configuration to monitor them may be slightly different. For [kubeadm](examples/jsonnet-snippets/kubeadm.jsonnet) and [bootkube](examples/jsonnet-snippets/bootkube.jsonnet) and [kops](examples/jsonnet-snippets/kops.jsonnet) clusters there are mixins available to easily configure these:

 Standard Kubernetes manifests are all written using [ksonnet-lib](https://github.com/ksonnet/ksonnet-lib/), so they can be modified with the mixins supplied by ksonnet-lib. For example to override the namespace of the node-exporter DaemonSet:
