     The resource group for the AKS cluster. Required when the registry (using the -r parameter) is set to "aks".
   -b | --build-solution
     Force a solution build before deployment (default: false).
-  -d | --dns <dns or ip address>
-    Specifies the external DNS/ IP address of the Kubernetes cluster. 
+  -d | --dns <dns or ip address> | --dns aks
+    Specifies the external DNS/ IP address of the Kubernetes cluster.
+    If 'aks' is set as value, the DNS value is retrieved from the AKS. --aks-name and --aks-rg are needed.
     When --use-local-k8s is specified the external DNS is automatically set to localhost.
   -h | --help
     Displays this help text and exits the script.
+  --image-build
+    Build images (default is to not build all images).
+  --image-push
+    Upload images to the container registry (default is not pushing to the custom registry)
   -n | --app-name <the name of the app>
     Specifies the name of the application (default: eshop).
+  --namespace <namespace name>
+    Specifies the namespace name to deploy the app. If it doesn't exists it will be created (default: eshop).
   -p | --docker-password <docker password>
     The Docker password used to logon to the custom registry, supplied using the -r parameter.
   -r | --registry <container registry>
     Specifies the container registry to use (required), e.g. myregistry.azurecr.io.
   --skip-clean
     Do not clean the Kubernetes cluster (default is to clean the cluster).
-  --skip-image-build
-    Do not build images (default is to build all images).
-  --skip-image-push
-    Do not upload images to the container registry (just run the Kubernetes deployment portion).
-    Default is to push the images to the container registry.
   --skip-infrastructure
     Do not deploy infrastructure resources (like sql-data, no-sql or redis).
     This is useful for production environments where infrastructure is hosted outside the Kubernetes cluster.
   -t | --tag <docker image tag>
-    The tag used for the newly created docker images. Default: newly created, date-based timestamp, with 1-minute resolution.
-  -u | --docker-user <docker username>
+    The tag used for the newly created docker images. Default: latest.
+  -u | --docker-username <docker username>
     The Docker username used to logon to the custom registry, supplied using the -r parameter.
   --use-local-k8s
     Deploy to a locally installed Kubernetes (default: false).
