+# Contour CRDs Helm Chart
+
+A lightweight Helm chart that installs only the CustomResourceDefinitions required by [Contour](https://projectcontour.io) and (optionally) the Gateway API. Use it when you want to manage CRDs centrally instead of bundling them with the main Contour release.
+
+## Prerequisites
+
+- Kubernetes 1.23+
+- Helm 3.8.0+
+
+## Installing the Chart
+
+To install the chart with the release name `contour-crds`:
+
+```console
+helm repo add contour https://projectcontour.github.io/helm-charts/
+helm repo update
+helm install contour-crds contour/contour-crds
+```
+
+## Using with the `contour` chart
+
+If you install CRDs through this chart, disable CRD management in the `contour` chart to avoid conflicts:
+
+```yaml
+contour:
+  manageCRDs: false
+```
+
+## Parameters
+
+| Name | Description | Value |
+| --- | --- | --- |
+| `contour.manageCRDs` | Manage the creation, upgrade and deletion of Contour CRDs. | `true` |
+| `gatewayAPI.manageCRDs` | Manage the creation, upgrade and deletion of Gateway API CRDs. | `false` |
+
+## Local testing
+
+Run basic linting and rendering checks before publishing:
+
+```console
+helm lint charts/contour-crds
+helm template charts/contour-crds --namespace default
+```
+
+Apply to a local cluster like minikube
+
+```console
+helm install contour-crds charts/contour-crds --namespace default
+# to install with the gateway api crds
+helm install contour-crds ./charts/contour-crds --namespace default --set gatewayAPI.manageCRDs=true
+# to remove
+helm uninstall contour-crds --namespace default
+```
