+## 1. Create a Kubernetes Cluster
 
 Creating an AKS cluster in Azure is easy. Simply click the ***Create a resource*** button at the top-left corner of the [Azure Portal](https://portal.azure.com), select the ***Containers** section and click on ***Kubernetes Service***. A dialog appears and guides you through the creation of your AKS cluster.

 In Kubernetes, authentication plays an important role. You might want to enable **RBAC (Role Base Access Control)**, to define, which team members and Kubernetes services are allowed to do what. For auto-scaling, the AKS cluster also needs a **service principal**. This is a virtual user in the Active Directory and defines, what a non-human service is allowed to do. We would want AKS to allow to spin up additional VMs as Worker Nodes, when needed.

 After some minutes, you AKS has been created successfully and you should be able to open you cluster overview in the Azure Portal. As Kubernetes itself works mostly command line based or through its own [Web UI (the Kubernetes dashboard)](https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/), there is not too much to see here. What users can manage from this portal is mostly related to the underlying hardware or the Kubernetes installation itself.

+## 3. Deploy the applications
 
 As mentioned, working with Kubernetes is mostly done via the command line. So you need the [`kubectl` tool](https://kubernetes.io/docs/tasks/tools/install-kubectl/) installed on your machine. Once you did this, you can connect your local environment with the AKS cluster.
 
-### Connect to the AKS cluster

 To configure `kubectl` to connect to your Kubernetes cluster, use the [`az aks get-credentials`](https://docs.microsoft.com/en-us/cli/azure/aks?view=azure-cli-latest#az-aks-get-credentials) command. This command downloads credentials and configures the Kubernetes CLI to use them.

 In Kubernetes, you work with manifest files. A Kubernetes manifest file defines a desired state for the cluster, such as what container images to run. In this workshop, a manifest is used to create all objects needed to run the samples. This manifest includes multiple [Kubernetes deployments](https://docs.microsoft.com/en-us/azure/aks/concepts-clusters-workloads#deployments-and-yaml-manifests). One for the Web API, one for the Chat Bot and so on. In addition, some [Kubernetes services](https://docs.microsoft.com/en-us/azure/aks/concepts-network#services) are created.
