 # Apigee OPDK Playbook Maintenance - Cassandra Replication Factor Change Runbook
 
-This is an Ansible playbook that performs a modification of Cassandra replication factor on Apigee
-components with Zero Downtime. 
+This is an Ansible playbook that performs a modification of the Cassandra replication factor used 
+with Apigee components with zero downtime in a two data center topology. 
 
-## Requirements and Usage
+## Requirements and Usage Overview
 
 This playbook uses ansible-galaxy to download roles that are used by this playbook. Once roles are 
 downloaded the playbook and be invoked in several ways. The playbook can be invoked in its entirety, 
 a tag can be used to invoke a subset of playbook services or the playbook may be run manually. These
 ways of invoking the playbook are described below. 
 
-## Download Roles
+## Description: Download Roles 
 
 The playbook roles and their location is found in the  ```requirements.yml``` file. This file is 
 provided to ```ansible-galaxy``` so that the roles may be downloaded.
 
-### ansible-galaxy usage
+### Usage: Ansible Galaxy 
+
+Ansible galaxy will download the required roles when invoked with the install action and the 
+requirements file. This is accomplished in the following way:
 
 ```ansible-galaxy install -r requirements.yml```
 
-### Usage: replication_factor_update.yml 
+### Update Replication Factor Overview
+ 
+The ```update-replication-factor.yml``` script performs the update of the Cassandra replication 
+factor for keyspaces in a Cassandra ring. This playbook assumes that you are changing Cassandra 
+replication on a planet that is composed of two regions or two data centers. 
 
-The ```replication_factor_update.yml``` requires that you specify the ```replication_factor```,
-```opdk_region``` and the ```hosts```. 
+This script expects you to provide the ```replication_factor``` setting you wish to use when the 
+script is invoked at the command line. 
 
-```ansible-playbook replication_factor_update.yml -e hosts=dc-1-ds -e opdk_region=dc-1 -e replication_factor=3```
+#### Usage: Full Playbook Invocation
+ 
+The full playbook invocation is performed in the following way: 
+
+    ansible-playbook update-replication-factor -e replication_factor=6 -vvv -b 
+    
+### Usage: Manaul Playbook Invocation
+
+This playbook enables tasks to be invoked manually. Manual invocation of this playbook is 
+accomplished in the following way: 
+ 
+    ansible-playbook update-replication-factor -e replication_factor=6 -vvv --step
+    
+During manual invocation the playbook will stop before every task. The user is prompted on each task  
+for permission to execute, stop execution or continue execution to the first task of the next play. 
+The prompt accepts ```y``` to execute; ```n``` to stop execution or ```c``` to continue execution 
+and stop on the first task of the next play. 
 
 ### Usage: update.yml 
 This playbook contains a convenience playbook that uses the ```replication_factor_update.yml```
