+# Percona XtraDB Cluster
+
+### Info:
+
+This template creates a Percona XtraDB Cluster on top of Rancher.
+
+When deployed from the catalog, a three node cluster is created with a database, root password, database user and password. The cluster is set up for replication between all of the nodes. Health check monitors port 8000 for clustercheck status updates.
+
+### Usage:
+
+Once deployed, use a mysql client to connect:
+
+`mysql -u<db_user> -p -h<pxc>`
