 ## Introduction
 
-The `peadm::add_replica` plan is designed to setup disaster recovery of a Primary Puppet Enterprise server. This is acheived through adding a primary replica to your system. Although this plan doesn't change your PE architcture, adding DR does depend on the structure of your current architecture.
+The `peadm::add_replica` plan is designed to setup disaster recovery (DR) of a Puppet Enterprise primary server. This is achieved by adding a primary replica to your system. Although this plan doesn't change your PE architecture, adding DR depends on the structure of your current architecture.
 
-In the case of Standard and Large installations, DR can be acheiveived by simply utilising this plan and adding the primary replica. In the case of an Extra Large infrastructure which includes an external DB, a replica DB is also required. This can be done with the `peadm::add_database` plan. For more detail see [Adding External Databases with peadm::add_database](expanding.md#adding-external-databases-with-peadmadd_database).
