-# Adding additional listeners to nodes based on the selector
+# Support configuring additional listeners to specific machines
 
 [Github Issue](https://github.com/kubernetes-sigs/cluster-api-provider-ibmcloud/issues/1678)
 ## Motivation
-Currently, when a listener pool is configured for a specific port (e.g., port 22), all machines are added to the pool.
-This creates a challenge when debugging OpenShift cluster deployments, as access to the bootstrap node is necessary for
-retrieving log files and other diagnostic data. Since all machines are included in the pool, SSH access to the bootstrap
-node becomes impossible.
+Currently, when configuring LoadBalancer's additional listeners, all the machines are added to the listener pool.
+This creates a challenge when you want to ssh into a particular machine.
 To address this, there should be a mechanism to assign listeners to specific machines using label selector matching.
