 Requirements
 ------------
 
-The Ansible setup module should be executed. 
+The installation of Apigee OPDK requires root access. Credentials must also be supplied to override the empty placeholders
+provided here. It is recommended that credentials be consolidated into a single credentials.yml file that can be stored 
+separately. It is assumed that files containing credentials are stored in the ~/.apigee folder.

 Dependencies
 ------------
 
-The role requires depends on the opdk-setup-installer and on the 
-execution of a profile that would configure the management server. We 
-can't associate the dependency to those roles until we can choose that a 
-given role from several has been applied. Currently this can be one of:
-- opdk-setup-aio
-- opdk-setup-ms
-- ( Standalone profile when we create that role :-) ) 
+This role depends on the following roles:
+
+* opdk-setup-default-settings
 
 Example Playbook
 ----------------
 
-Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
-
     ---
     - hosts: '{{ hosts }}'
       become: yes
       
       roles:
-        - <Some role profile that installs and configures a management server>
-        - opdk-setup-org
+      - { role: opdk-setup-org }
+
