2. Because the `bootstrap` Kustomization includes everything **recursively** under `bootstrap` path in the repo, all of the above were **also** applied to the cluster
3. I'd pre-prepared a [Namespace](https://github.com/geek-cookbook/template-flux/blob/main/bootstrap/namespaces/namespace-podinfo.yaml), [HelmRepository](https://github.com/geek-cookbook/template-flux/blob/main/bootstrap/helmrepositories/helmrepository-podinfo.yaml), and [Kustomization](https://github.com/geek-cookbook/template-flux/blob/main/bootstrap/kustomizations/kustomization-podinfo.yaml) for "podinfo", a simple example application, so these were applied to the cluster
4. The kustomization we added for podinfo refers to the `/podinfo` path in the repo, so everything in **this** folder was **also** applied to the cluster
5. In the `/podinfo` path of the repo is a [HelmRelease](https://github.com/geek-cookbook/template-flux/blob/main/podinfo/helmrelease-podinfo.yaml) (*an object describing how to deploy a helm chart*), and a [ConfigMap](https://github.com/geek-cookbook/template-flux/blob/main/podinfo/configmap-pofinfo-helm-chart-value-overrides-configmap.yaml) (*which ontain the `values.yaml` for the podinfo helm chart*)

6. Flux recognized the podinfo **HelmRelease**, applied it along with the values in the **ConfigMap**, and consequently we have podinfo deployed from the latest helm chart, into the cluster, and managed by Flux! 💪

Now we're into the external-dns-specific YAMLs. First, we create a ConfigMap, containing the entire contents of the helm chart's [values.yaml](https://github.com/bitnami-labs/external-dns/blob/main/helm/external-dns/values.yaml). Paste the values into a `values.yaml` key as illustrated below, indented 4 tabs (*since they're "encapsulated" within the ConfigMap YAML*).
