+# This files generally tries to match the naming conventions for a
+# kustomization.yaml with `helmCharts`, but has some mostly necessary
+# deviations.
+#
+# Field names matching `helmCharts` from a kustomization.yaml:
+# ------------------------------------------------------------------------------
+#
+# These values have the same name and function as in a `helmCharts` stanza.
+#
+# - repo: URL for the repo for the chart
+# - name: name of the chart to install from the repo
+# - namespace: The namespace to install in.
+#     - This will often, but only incidentally, match the `releaseName`.
+# - releaseName: identical to a `helmCharts` entry
+#      - However, since we install with a script, actually shows up as a release
+#        with `helm list`.
+#      - This will often, but only incidentally, match the `name`.
+#
+# Field names matching `helmCharts` from a kustomization.yaml, optional:
+# ------------------------------------------------------------------------------
+#
+# - version: Specify a chart version.
+#
+# Slightly different from `helmCharts` in a `kustomization.yaml`:
+# ------------------------------------------------------------------------------
+#
+# This shows slight differences between a `helmCharts` stanza and what you put
+# here.
+#
+# - valuesFiles: This includes all values files listed in order to apply them.
+#     - A separate `valuesFile` field seems unnecessary, so this should
+#       frequently have `values.yaml` as the first, and often the only, list
+#       entry.
+#     - Notably, subsumes the functionality of `additionalValuesFiles` from
+#       a `helmConfig`, as it simply applies all specified values files in
+#       order.
+#
+# - first line as _Genestack_ component name
+#    - `helmCharts` takes a list and has a `name` field that refers to the
+#       name of the chart from the repo. For the purpose of identifying the
+#       _Genestack_ component, the identification for each entry will
+#       frequently duplicate the `name` as used to identify a chart in the
+#       repo, but may or may not differ, e.g., `prometheus:` refers to
+#       Prometheus proper as a _Genestack_ component, but has `name`
+#       `kube-prometheus-stack` as the chart name from the repo, while
+#       `prometheus-pushgateway:` ALSO has `name: prometheus-pushgateway` as
+#       overall top-level identifier matching the `name.
+#
+# Required here but not in a stanza of `helmCharts`
+# ------------------------------------------------------------------------------
+#
+# This doesn't appear in a `helmCharts` stanza of a `kustomization.yaml`, but
+# you have to supply it here.
+#
+# - repoName: name for the repo as shown by `helm repo list`.
+#    - Using `kustomization.yaml` doesn't create a repo shown by
+#      `helm repo list` so this needed adding.
+#
+# Not required here and not in a stanza of `helmCharts`
+# ------------------------------------------------------------------------------
+#
+# - timeout: amount of time allowed for `helm install` to complete
+#    - optional because it defaults to 10m
+#    - no equivalent exists in a `helmCharts` stanza
+# - overlayDir: name of directory under
+#   /etc/genestack/kustomize/<SERVICE_NAME>/ for base or overlays.
+#    - optional, defaults to 'overlay'
+#
+# Notable differences
+# ------------------------------------------------------------------------------
+# - includeCRDs: not used
+#     - This often gets used in `helmCharts` in kustomization.yaml, but
+#       invoking `helm` directly installs CRDs by default unless you
+#       specify `--skip-crds`, so doesn't appear here.
+# - additionalValuesFiles: not used
+#     - As mentioned above, this list just goes under `valuesFiles` here, where
+#       all items of the list get applied in order.
