Rework documentaton to actually get people rolling

Individuals are beginning to evaluate Kolla and our quickstart
documentation is in terrible terrible shape.  Pleae just approve
this change but do leave feedback.  I will address changes in
an iterative process in future patches rather then having a
perfect documentation patch in one bang.

Since this isn't code, there is not a high cost to refactoring
or risk of regressions.

-Developer Environment
-=====================
+Quickstart to Deploying OpenStack using Ansible
+===============================================
 
-If you are developing Kolla on an existing OpenStack cloud that supports
-Heat, then follow the Heat template
-`README <https://github.com/stackforge/kolla/blob/master/devenv/README.md>`__.
-Another option available on systems with VirutalBox is the use of
-`Vagrant <https://github.com/stackforge/kolla/blob/master/docs/vagrant.md>`__.
+Evaluation and Developer Environments
+-------------------------------------
 
-The best experience is available with bare metal deployment by following
-the instructions below to manually create your Kolla deployment.
+Two virtualized evaluation and development environment options are
+available.  These options permit the evaluation of Kolla without
+disrupting the host operating system.
+
+If developing or evaluating Kolla on an OpenStack cloud environment that
+supports Heat, follow the
+`Heat evaluation and developer environment guide <https://github.com/stackforge/kolla/blob/master/docs/devenv-heat.rst>`__.
+
+If developing or evaluating Kolla on a system that provides VirtualBox,
+Vagrant may be used and is documented in the
+`Vagrant evaluation and developer environment guide <https://github.com/stackforge/kolla/blob/master/docs/devenv-vagrant.rst>`__.
+
+If evaluating or deploying OpenStack on bare-metal with Kolla, follow the
+instructions in this document to get started.
 
 Installing Dependencies
 -----------------------
 
-NB: Kolla will not run on Fedora 22 or later. Fedora 22 compresses
-kernel modules with the .xz compressed format. The guestfs system cannot
-read these images because a dependent package supermin in CentOS needs
-to be updated to add .xz compressed format support.

+Kolla deploys OpenStack using
+`Ansible <https://ansible.com>`__.  Install Ansible from distribution
+packaging if the distro packaging has 1.8.4 or greater available.  Currently
+Ubuntu's version of Ansible is too old to use from packaging.  On RPM
+based systems install from packaging using:
+
+::
+
+    yum -y install ansible
+
+On DEB based systems this can be done using:
+
+::
+
+    apt-get install ansible
+
+If the distro packaged version of Ansible is too old, install Ansible using
+pip:
+
+::
+
+    pip install -U ansible
+
+Buildling Container Images
+--------------------------
+
+The Kolla community does not currently generate new images for each commit
+to the repository.  The push time for a full image build to the docker registry
+is about 5 hours on 100mbit Internet, so there are technical limitations to
+using the Docker Hub registry with our current OpenStack CI/CD systems.
+
+The Kolla community builds and pushes tested images for each tagged release of
+Kolla, but if running from master, it is recommended to build images locally.
+All Docker images can be built as follows:
+
+::
+
+    tools/build.py -T 1000
+
+The -T option specifies how many threads to run concurrently.  A docker build
+of all containers on Xeon hardware with SSDs and 100mbit network takes roughly
+15 minutes.  The CentOS mirrors are flakey and the RDO delorean repository is
+not mirrored at all.  As a result occasionally some containers will fail to
+build.  If something important fails to bulid, repeat the entire build process
+again.  The Kolla community recognizes this is not ideal and the Kolla
+community is adding an individual container build option to solve this
+particular problem.
 
 Starting Kolla
 --------------
 
-Configure Ansible by reading the Kolla
-`Ansible configuration <https://github.com/stackforge/kolla/blob/master/docs/ansible-deployment.md>`__ documentation.

-Next, run the start command:
+Finally, run the deploy operation:
 
 ::
 
     $ sudo ./tools/kolla-ansible deploy

-takes five minutes to deploy AIO. These are estimates; your hardware may
-be faster or slower but should near these results.

 Debugging Kolla

+The container's status can be determined on the deployment targets by
+executing:

-If any of the containers exited you can check the logs by executing:
+If any of the containers exited, this indicates a bug in the container.  Please
+seek help by filing a bug or contacting the developers via IRC.
+
+ the logs can be examined by executing:
 
 ::
 
-    $ sudo docker logs <container-name>
+    $ docker logs <container-name>
 
+Note some of the containers don't log to stdout at present so the above
+command will provide no information.  Instead they log to files
+in _/var_/log_/_<service_> inside the container.  The Kolla community is
+working to improve auditing and make things more consistent.  The Kolla
+community expects this work to complete by Liberty rc1.  An example of
+reading the logs for nova-api:
+
+::
+    $ docker exec -t nova_api more /var/log/nova/nova-api.log
+
+Note reading the logs via an exec operation can only be done if the
+container is running.
