+== Managing Remote Clusters
+
+{kib} *Management* provides two user interfaces for working with data from remote 
+clusters. 
+
+*Remote Clusters* helps you manage remote clusters for use with 
+{ref}/modules-cross-cluster-search.html[cross cluster search] and 
+{xpack-ref}/xpack-ccr.html[cross cluster replication]. You can add and remove remote 
+clusters and check their connectivity. 
+
+Go to *Management > Elasticsearch > Remote Clusters* to get started.

+
+
+*Cross Cluster Replication* includes tools to help you create and manage the remote 
+replication process.  You can follow an index pattern on the remote cluster for 
+auto-discovery and then replicate new indices in the local cluster that match the 
+auto-follow pattern.
