 Jsonnet has the concept of hidden fields. These are fields, that are not going to be rendered in a result. This is used to configure the kube-prometheus components in jsonnet. In the example jsonnet code of the above [Customizing Kube-Prometheus section](#customizing-kube-prometheus), you can see an example of this, where the `namespace` is being configured to be `monitoring`. In order to not override the whole object, use the `+::` construct of jsonnet, to merge objects, this way you can override individual settings, but retain all other settings and defaults.
 
-These are the available fields with their respective default values:
-```
-{
-	_config+:: {
-    namespace: "default",
-
-    versions+:: {
-        alertmanager: "v0.17.0",
-        nodeExporter: "v0.18.1",
-        kubeStateMetrics: "v1.5.0",
-        kubeRbacProxy: "v0.4.1",
-        prometheusOperator: "v0.30.0",
-        prometheus: "v2.10.0",
-    },
+The available fields and their default values can be seen in [main.libsonnet](jsonnet/kube-prometheus/main.libsonnet). Note that many of the fields get their default values from variables, and for example the version numbers are imported from [versions.json](jsonnet/kube-prometheus/versions.json).

-        prometheus: "quay.io/prometheus/prometheus",
-        alertmanager: "quay.io/prometheus/alertmanager",

-        nodeExporter: "quay.io/prometheus/node-exporter",
-        prometheusOperator: "quay.io/prometheus-operator/prometheus-operator",
-    },
+Configuration is mainly done in the `values` map. You can see this being used in the `example.jsonnet` to set the namespace to `monitoring`. This is done in the `common` field, which all other components take their default value from. See for example how Alertmanager is configured in `main.libsonnet`:

-        names: 'k8s',

 ### Adding additional namespaces to monitor
