 To add the label of `foo=bar` to a node from a VMSS pool, you would add the following tag to the VMSS `k8s.io_cluster-autoscaler_node-template_label_foo: bar`.
 
-You can also use forward slashes in the labels by setting them as an underscore in the tag name. For example to add the label of `k8s.io/foo=bar` to a node from a VMSS pool, you would add the following tag to the VMSS `k8s.io_cluster-autoscaler_node-template_label_k8s.io_foo: bar`. To encode a tag name containing an underscore, use "~2" (eg. "cpu~2arch" gives "cpu_arch").
