+========
+Overview
+========
+
+This HELM project wraps Haproxy Ingress Controller helm chart as a dependency, when installed - this will setup a HAProxy Ingress Controller with two pods and a service.
+
+To build this project, run -
+    helm dep up hdp-lb-server-deploy
+
+This will download the chart to /charts directory.
+
+The .values.yaml has the basic configuration needed for the HAProxy Ingress Controller HELM project setup.  Based on the need, values can be finetuned further.
+
+Refer to this wiki page for more details - https://progresssoftware.atlassian.net/wiki/spaces/DataDirectRandD/pages/541753550/Deploying+HDP+Server+on+Azure+Kubernetes+Service+AKS
+
+================
+Steps to Install
+================
+
+helm install haproxy-deploy haproxy-deploy --namespace haproxy-controller -create-namespace -f values.yaml
+
+This would install necessary resources, to get the external IP for the HAProxy Controller Service,
+run the command kubectl get svc and check the External - IP column.
+
+'A' record should be mapped to this IP address for the valid dns hostname in a valid dns zone.
+
+As an example, this is the default dns zone offerred by Azure AKS accessible over public internet.
+To access HDP would be something like - http://hdp.2565fbe255034c49a07b.eastus.aksapp.io/
+
+================
+Useful Commands
+================
+
+helm install haproxy-deploy haproxy-deploy --namespace haproxy-controller --create-namespace -f values.yaml
+
+helm list --namespace haproxy-controller
+
+kubectl get svc --namespace haproxy-controller
+
+kubectl get pods --namespace haproxy-controller
+
+helm uninstall haproxy-deploy --namespace haproxy-controller
