 ## Limitations
 
 The remote cluster state functionality has the following limitations:
 - Unsafe bootstrap scripts cannot be run when the remote cluster state is enabled. When a majority of cluster-manager nodes are lost and the cluster goes down, the user needs to replace any remaining cluster manager nodes and reseed the nodes in order to bootstrap a new cluster.
 
-## Remote Cluster State Publication
-The cluster state published to remote-backed storage can be used for publication. Currently, the active cluster manager
-sends the cluster state object over the transport layer to the follower nodes. This flow can be changed to fetch the
-cluster state from remote store. This can be done by enabling the experimental remote publication feature. 
+## Remote cluster state publication
+Cluster state publication via remote - When it is enabled, the updated cluster state during any updates like creation of an index and 
+put mappings will be published via remote store, that is, the cluster manager will provide the remote location 
+and nodes will download the cluster state directly from remote location. 
+As the cluster state grows over time and there are large number of nodes in the cluster, publishing the state over local transport
+tends to add lot of overhead in terms of cpu, memory and transport threadpool. This will reduce the overhead on cluster manager node
+to publish the updated cluster state via remote store to every other node in the cluster instead of local transport.
+Remote cluster state publication can be enabled by configuring the experimental remote publication feature. 
 Enable the feature flag for `remote_store.publication` feature by following the [experiment feature flag documentation]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/experimental/).
-When remote publication is enabled, the cluster manager node uploads the cluster state to remote store and then sends the 
-remote path of the cluster state to the follower nodes. The follower nodes then download the cluster state from remote store.
 
 The routing table is an object within the cluster state which contains the shard allocation details for each index.
 This object can become large in case of large number of shards in the cluster. Routing table is required to be stored in
-remote store for the remote publication to work. In order to enable remote persistence of routing table, the repository must
-be configured as below:
