+# NGINX App chart
+
+This chart allows you to deploy a simple web application container running nginx, and provides a service and ingress to the application
+
+
+## Install Chart
+
+To install the Chart into your Kubernetes cluster :
+
+```bash
+helm install --name "mywebapp" pnnl-miscscripts/chronyd --set image.repository=nginx
+```
+
+After installation succeeds, you can get a status of Chart
+
+```bash
+helm status "mywebapp"
+```
+
+If you want to delete your Chart, use this command:
+
+```bash
+helm delete  --purge "mywebapp"
+```
