+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.

+IVOA Registry Service Helm Chart
+
+| Chart | AppVersion | Type |
+|:-----:|:----------:|:----:|
+|1.2.0<!-- x-release-please-version --> | 1.2.1 | application |
+
+## Overview
+
+This Helm chart deploys the **reg** IVOA Registry Service on Kubernetes.
+
+The chart runs the application built from the [`reg/`](../reg/) directory in this repository — the deployable WAR, Docker image, and runtime configuration described in [`reg/README.md`](../reg/README.md). Other modules in the repository (`cadc-registry`, `cadc-vosi`, and so on) are libraries consumed by that application; this chart does not deploy them separately.
+
+The default container image is `images.opencadc.org/core/reg`, with tag matching the chart `appVersion` (aligned with [`reg/VERSION`](../reg/VERSION)).
+
+## Install
+
+From the repository root:
+
+```bash
+helm install my-reg ./helm -f my-values.yaml
+```
+
+`application.serviceEntries` is required. A minimal values file:
+
+```yaml
+application:
+  serviceEntries:
+    - id: "ivo://example.org/reg"
+      url: "https://example.org/my-service/capabilities"
+```
+
+## Configuration
+
+The chart renders a ConfigMap mounted at `/config` in the container. That produces the property files documented in [`reg/README.md`](../reg/README.md):
+
+| ConfigMap key | Purpose |
+|---------------|---------|
+| `catalina.properties` | Tomcat and proxy settings (`tomcat.connector.*`) |
+| `reg-resource-caps.properties` | VOSI-enabled API entries (from `application.serviceEntries`) |
+| `reg-applications.properties` | Web application entries (from `application.applicationEntries`, optional) |
+| `cadc-log.properties` | Dynamic logging control (optional) |
+
+### Application settings (`application.*`)
+
+- **`application.serviceEntries`** (required): list of `{ id, url }` pairs for VOSI-enabled APIs (web services). Rendered into `reg-resource-caps.properties` ([reg-resource-caps.properties](https://github.com/opencadc/reg/tree/main/reg#reg-resource-capsproperties-optional)).
+- **`application.logging`**: users, groups, or DNs granted enhanced logging.
+- **`application.applicationEntries`**: optional web application (user interface) feature ID to URL mappings ([reg-applications.properties](https://github.com/opencadc/reg/tree/main/reg#reg-applicationsproperites-optional-experimental)).
+
+### Public URL (`tomcat.connector`)
+
+When the service sits behind a reverse proxy, Tomcat needs the public URL clients use (equivalent to `X-Forwarded-Proto`, `X-Forwarded-Host`, and `X-Forwarded-Port`). These values are written to `catalina.properties` as `tomcat.connector.*` and affect VOSI capabilities output: `accessURL` hostnames are rewritten to match the request URL.
+
+Resolution order for each field:
+
+1. Explicit value in `tomcat.connector`
+2. Auto-derived from `httpRoute` (if enabled) or `ingress` (if enabled)
+3. Omitted when `proxyName` cannot be resolved
+
+**Internal-only deployment (defaults):** with `ingress.enabled=false`, `httpRoute.enabled=false`, `service.type=ClusterIP`, and empty `tomcat.connector` fields, no `tomcat.connector.*` properties are emitted. The service stays ClusterIP-only (reachable by Pods in the cluster) and Tomcat uses each incoming request URL as-is.
+
+Set `tomcat.connector` explicitly when the public URL differs from the ingress or HTTPRoute hostname — for example, when a CDN or external load balancer sits in front of the cluster.
+
+### Service exposure
+
+| Mechanism | Values key | Default |
+|-----------|------------|---------|
+| In-cluster only | `service.type: ClusterIP` | yes |
+| Ingress | `ingress.enabled` | `false` |
+| Gateway API HTTPRoute | `httpRoute.enabled` | `false` |
+
+When ingress or HTTPRoute is enabled and `tomcat.connector` fields are left empty, the public URL is derived from the configured hostnames.
+
