+# Basic Helm Template for Deploying Microservice on K8s
+
+## Chart Structure
+```
+microservice/
+├── Chart.yaml
+├── values.yaml
+├── charts/
+└── templates/
+    ├── deployment.yaml
+    └── service.yaml
+```
+
+## Usage
+
+You can change the Docker image by modifying the values.yaml file. For example, to use a different image, update the `image.repository` and `image.tag` fields.
+
+The Helm chart is specifically for deploying a microservice with a Kubernetes service and deployment. You can further customize and expand this chart as needed for your application.
+
+## Installing the Chart on K8s
+
+```bash
+helm install my-release microservice/
+```
