+# Portworx BBQ Helm Chart
+
+This chart will install the **Portworx BBQ (pxbbq)** demo application in a Kubernetes cluster ([source](https://github.com/theITHollow/shanksbbq)).
+
+You can learn more about it by looking at [Azure/kubernetes-hackfest](https://github.com/Azure/kubernetes-hackfest/blob/master/labs/storage/portworx/README.md) repository.
+
+## Quick start
+
+Install the app with default settings:
+
+```bash
+# adds the repo
+helm repo add suse-lab-setup https://opensource.suse.com/lab-setup
+helm repo update
+
+# installs the chart
+helm upgrade --install portworx-bbq suse-lab-setup/portworx-bbq --namespace pxbbq --create-namespace
+```
+
+Look at [values.yaml](values.yaml) for the configuration.
+
+Clean-up:
+
+```bash
+helm delete portworx-bbq --namespace pxbbq
+kubectl delete ns pxbbq
+```
+
+## Chart dependencies
+
+### MongoDB chart
+
+Add Helm repo:
+
+```bash
+helm repo add bitnami https://charts.bitnami.com/bitnami
+```
+
+Search for the latest package:
+
+```bash
+helm search repo -l mongodb --versions
+```
+
+Update `Chart.yaml`.
+
+Update `Chart.lock`:
+
+```bash
+helm dependency update
+```
