Description of problem:

In section 1.1 of the doc for Repository Configuration, the steps are roughly as follows:

1. sudo subscription-manager register
2. sudo subscription-manager list --available
3. sudo subscription-manager subscribe --pool=POOLID
4. sudo yum-config-manager --disable rhel-server-ost-6-preview-rpms
5. sudo yum-config-manager --enable rhel-server-ost-6-folsom-rpms
6. sudo yum-config-manager --enable rhel-6-server-beta-rpms
7. sudo yum repolist

This set of steps will fail for most people, because /etc/yum.repos.d/redhat.repo is not populated with repositories until after the first yum repolist command is run.  So the yum-config-manager steps in 4/5/6 end up being ineffective, since there is no yum repo configuration for them to act on.

Instead we need an extra step here:
3.5. sudo yum repolist

Inserting the yum repolist here will populate the redhat.repo file, and then the subsequent yum-config-manager steps will have effect.

Also, we should provide sample output for each of the yum repolist commands so that folks know what to expect at each step from yum repolist.

It should look like this:

repo id                       repo name                                   status
rhel-6-server-beta-rpms       Red Hat Enterprise Linux 6 Server Beta (RPMs)1,103
rhel-6-server-rpms            Red Hat Enterprise Linux 6 Server (RPMs)     8,770
rhel-server-ost-6-folsom-rpms Red Hat OpenStack Folsom Preview (RPMs)      138
repolist: 11,066

(Note, I omitted a bunch of other irrelevant repos, the above three are the ones to make sure that are present)

It should also be noted that the output of yum-config-manager --enable should be to show the configuration for the repository that you just enabled.  For example, yum-config-manager --enable on the RHEL 6.4 beta repo shows this:
