 ### Set node pool taints
 
-1. Create a node pool with a taint using the [`az aks nodepool add`][az-aks-nodepool-add] command. Specify the name *taintnp* and use the `--node-taints` parameter to specify *sku=gpu:NoSchedule* for the taint.

-    az aks nodepool add \
-        --resource-group myResourceGroup \

-        --no-wait

-2. Check the status of the node pool using the [`az aks nodepool list`][az-aks-nodepool-list] command.

-The taint information is visible in Kubernetes for handling scheduling rules for nodes. The Kubernetes scheduler can use taints and tolerations to restrict what workloads can run on nodes.
-
-* A **taint** is applied to a node that indicates only specific pods can be scheduled on them.
-* A **toleration** is then applied to a pod that allows them to *tolerate* a node's taint.
+AKS supports two kinds of node taints: node taints and node initialization taints (preview). For more information, see [Use node taints in an Azure Kubernetes Service (AKS) cluster][use-node-taints].
