 In this task, you will install Prometheus on your Kubernetes (K8s) cluster using a Helm chart and configure it to collect essential cluster-specific metrics.
 
 ## Steps
-
 1. **Install Prometheus**
-
    - Follow the instructions to install Prometheus using the Helm chart by Bitnami. Refer to the [Prometheus documentation](https://prometheus.io/docs/introduction/overview/) for more details.
-   - Ensure Prometheus is not exposed outside (i.e., it cannot be accessed directly from the internet).
-
+2. **Install Exporters**
+   - Install necessary exporters to collect metrics from Kubernetes components.
+3. **Configure Prometheus**
+   - Configure Prometheus to get metrics from Kubernetes components.
 2. **Verify Metrics Collection**
-   - Ensure Prometheus is collecting essential cluster-specific metrics, such as nodes' CPU and memory usage.
-   - Check the collected metrics via Prometheus web interface using `kubectl proxy` or `port-forward`.
+   - Ensure Prometheus is collecting essential cluster-specific metrics, such as nodes' memory usage.
+   - Check the collected metrics via Prometheus web interface.
 
 ## Submission
-
-- Provide a PR with the Helm chart and configuration files for Prometheus deployment in a new repository.
-- Ensure that Prometheus is installed and collecting cluster-specific metrics.
-- Provide a README file documenting the Prometheus setup, including the custom dashboard.
+- Provide a PR with automation of a Prometheus deployment in Kubernetes.
+- Provide an output of `kubectl get pods` with running Prometheus.
+- Include a screenshot of any metrics (e.g. node disk space usage) shown in the Prometheus web UI.
+- Provide a README file documenting the Prometheus deployment and configuration.
