Install and Deploy Manual needs clearer nova volume instructions

So, it's sort of buried in this page:
http://docs.openstack.org/trunk/openstack-compute/install/content/compute-assumptions-installation.html

as an assumption. I will pull it out more specifically like the Hastexo guide does though:
http://www.hastexo.com/resources/docs/installing-openstack-essex-4-ubuntu-1204-precise-pangolin/appendix-making-nova-volume

This is what i did to get dashboard working.

1. created a tenant name admin
2. created user admin and demo
3. added role admin for user admin
4. added role Member for demo user (Dashboard needs a member role)

1. Created a Tenant name service
2. added all the services (swift/glance/nova) as users inside this tenant.
3. added admin role for all the users for this tenant

Created services, including swift

# Create required services
keystone service-create --name nova --type compute --description 'OpenStack Compute Service'
keystone service-create --name swift --type object-store --description 'OpenStack Storage Service'
keystone service-create --name glance --type image --description 'OpenStack Image Service'
keystone service-create --name keystone --type identity --description 'OpenStack Identity Service'
keystone service-create --name ec2 --type ec2 --description 'EC2 Service'
keystone service-create --name volume --type volume --description 'Volume Service'

 Added Endpoints for all

Installed openstack-dashboard package and memcached

I got it working.

Sorry I didn't point out which manual exactly I am referring to
it is this one http://docs.openstack.org/trunk/openstack-compute/install/content/

I know how to install and setup this, but it's confusing for beginner if they are following this manual above
