 ### Setting nodepool Azure tags
 
-You can apply an Azure tag to node pools in your AKS cluster. Tags applied to a node pool are applied to each node within the node pool and are persisted through upgrades. Tags are also applied to new nodes added to a node pool during scale-out operations. Adding a tag can help with tasks such as policy tracking or cost estimation.
-
-Azure tags have keys which are case-insensitive for operations, such as when retrieving a tag by searching the key. In this case a tag with the given key will be updated or retrieved regardless of casing. Tag values are case-sensitive.
-
-In AKS, if multiple tags are set with identical keys but different casing, the tag used is the first in alphabetical order. For example, `{"Key1": "val1", "kEy1": "val2", "key1": "val3"}` results in `Key1` and `val1` being set.
-
-Create a node pool using the [az aks nodepool add][az-aks-nodepool-add]. Specify the name *tagnodepool* and use the `--tag` parameter to specify *dept=IT* and *costcenter=9999* for tags.
-
-```azurecli-interactive
-az aks nodepool add \
-    --resource-group myResourceGroup \
-    --cluster-name myAKSCluster \
-    --name tagnodepool \
-    --node-count 1 \
-    --tags dept=IT costcenter=9999 \
-    --no-wait
-```
-
-> [!NOTE]
-> You can also use the `--tags` parameter when using [az aks nodepool update][az-aks-nodepool-update] command as well as during cluster creation. During cluster creation, the `--tags` parameter applies the tag to the initial node pool created with the cluster. All tag names must adhere to the limitations in [Use tags to organize your Azure resources][tag-limitation]. Updating a node pool with the `--tags` parameter updates any existing tag values and appends any new tags. For example, if your node pool had *dept=IT* and *costcenter=9999* for tags and you updated it with *team=dev* and *costcenter=111* for tags, you nodepool would have *dept=IT*, *costcenter=111*, and *team=dev* for tags.
-
-The following example output from the [az aks nodepool list][az-aks-nodepool-list] command shows that *tagnodepool* is *Creating* nodes with the specified *tag*:
-
-```azurecli
-az aks nodepool list -g myResourceGroup --cluster-name myAKSCluster
-```
-
-```output
-[
