+# validate-domain
+
+Validate that a Helm chart (`Chart.yaml`) contains an `annotations.domain` value that is one of a configured set of allowed domains.
+
+## ✨ What It Does
+
+The action:
+Checks if the `Chart.yaml` has the "domain" annotation and validates that the domain is in the domains list
+
+## Inputs
+
+| Name | Required | Default | Description |
+|------|----------|---------|-------------|
+| `chart-file` | no | `helm/Chart.yaml` | Path to the Helm chart file whose `annotations.domain` will be validated. |
+
+The set of allowed domains is constant (not configurable):
+
+```
+raster, vector, infra, 3d, app, dem, common
+```
+
+If you need to change or extend this list, update the action source or open a PR.
+
+
+## 🚀 Usage
+
+<!-- x-release-please-start-version -->
+```yaml
+      - name: Validate domain
+        uses: MapColonies/shared-workflows/actions/validate-domain@v1
