Description of problem:
In section 3.2.6 of the install guide step 5 addresses running the ansible-playbook to create the Ceph cluster. This step assumes the user is in the directory where the site.yml resides. We should clarify this command needs to be run in the directory where the site.yml resides.

5. As root, run the Ansible playbook:

# ansible-playbook site.yml [-u <user_name>]

Once the playbook runs, it creates a running Ceph cluster. 

We could say:

5. As root, run the Ansible playbook from the directory where the playbook resides:

# ansible-playbook site.yml [-u <user_name>]

Once the playbook runs, it creates a running Ceph cluster.
