 ## Example Usage
 
+There are two ways to use `bigip_ltm_pool_attachment` resource for `node` attribute
 
-There are two ways to use ltm_pool_attachment resource, where we can take node reference from ltm_node or we can specify node directly with ip:port/fqdn:port which will also create node and atach to pool.
+* It can be reference from `bigip_ltm_node` (or)
+* It can be specify directly with `ipv4:port`/`fqdn:port`/`ipv6.port` which will also create node and attach member to pool.
 
+~> For adding IPv6 node/member to pool it should be specific in `node` attribute in format like `ipv6_address.port`.
+IPv4 should be specified as `ipv4_address:port`
