+# Helm Chart Tests
+
+To test that the deployment-operator Helm chart can be successfully installed, run:
+
+```sh
+./test/helm/test-chart-install.sh
+```
+
+This script will:
+1. Create a temporary Kind cluster
+2. Validate the chart using `helm lint`
+3. Verify template rendering with `helm template`
+4. Perform a dry-run installation with `helm install --dry-run`
+5. Automatically clean up the cluster when the test completes
+
+See [test/helm/README.md](test/helm/README.md) for more details.

+# Helm Chart Tests
+
+This directory contains tests for the Helm charts in the deployment-operator project.
+
+## Running the Chart Installation Test
+
+The `test-chart-install.sh` script verifies that the deployment-operator Helm chart can be successfully installed in a Kubernetes cluster.
+
+### Prerequisites
+
+The script requires the following tools to be installed:
+
+- [Helm](https://helm.sh/docs/intro/install/) (v3.x)
+- [Kind](https://kind.sigs.k8s.io/docs/user/quick-start/#installation) 
+- [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl)
+
+### Usage
+
+From the root of the repository, run:
+
+```bash
+./test/helm/test-chart-install.sh
+```
+
+The script will:
+
+1. Create a temporary Kind cluster with a unique name
+2. Validate the chart using `helm lint`
+3. Verify template rendering with `helm template`
+4. Perform a dry-run installation with `helm install --dry-run`
+5. Automatically clean up the cluster when the test completes
+
+### CI/CD Integration
+
+This test is also integrated into GitHub Actions workflows to catch Helm chart issues in PRs and pushes to the main branch.
