Alexander, can you add some more details about what we need to document, and for which version(s)?
Comment 2 Alexander Chuzhoy 2017-07-04 15:26:13 UTC 
I see it's already updated here:
"""
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html/director_installation_and_usage/chap-planning_your_overcloud
Section 3.1:
3.1. Planning Node Deployment Roles

The director provides multiple default node types for building your overcloud. These node types are:

Controller

    Provides key services for controlling your environment. This includes the dashboard (horizon), authentication (keystone), image storage (glance), networking (neutron), orchestration (heat), and high availability services (if using more than one Controller node). A Red Hat OpenStack Platform environment requires either:

        One node for a basic environment
        Three nodes for a highly available environment 

    Environments with two nodes or more than three nodes are not supported. 
"""


Previously one could assume 2 are also supported.
