+# Helm chart for game 2048
+
+This Helm chart will install Game 2048 on a Kubernetes cluster.
+
+## Usage
+
+[Helm](https://helm.sh) must be installed to use the chart from the command line. Here is the flow to have the application running in your Kubernetes cluster:
+
+```bash
+# adds the repo (if not already done)
+helm repo add devpro https://devpro.github.io/helm-charts
+
+# retrieves recent information from added repos
+helm repo update
+
+# installs the chart (this command can be ran multiple times)
+helm upgrade --install game-2048 devpro/game-2048 --create-namespace --namespace sample-apps
+```
+
+Once done, uninstall the chart and clean-up the cluster:
+
+```bash
+helm delete game-2048
+kubectl delete ns sample-apps
+```
