+Overview
+========
+
+The OpenStack Dashboard provides a Django based web interface for use by both
+administrators and users of an OpenStack Cloud.
+
+It allows you to manage Nova, Glance, Cinder and Neutron resources within the
+cloud.
+
+Usage
+=====
+
+The OpenStack Dashboard is deployed and related to keystone:
+
+    juju deploy openstack-dashboard
+    juju add-unit openstack-dashboard keystone
+
+The dashboard will use keystone for user authentication and authorization and
+to interact with the catalog of services within the cloud.
+
+The dashboard is accessible on:
+
+    http(s)://service_unit_address/horizon
+
+At a minimum, the cloud must provide Glance and Nova services.
+
+SSL configuration
+=================
+
+To fully secure your dashboard services, you can provide a SSL key and
+certificate for installation and configuration.  These are provided as
+base64 encoded configuration options::
+
+    juju set openstack-dashboard ssl_key="$(base64 my.key)" \
+        ssl_cert="$(base64 my.cert)"
+
+The service will be reconfigured to use the supplied information.
+
+High Availability
+=================
+
+The OpenStack Dashboard charm supports HA in-conjunction with the hacluster
+charm:
+
+    juju deploy hacluster dashboard-hacluster
+    juju set openstack-dashboard vip="192.168.1.200"
+    juju add-relation openstack-dashboard dashboard-hacluster
+    juju add-unit -n 2 openstack-dashboard
+
+After addition of the extra 2 units completes, the dashboard will be
+accessible on 192.168.1.200 with full load-balancing across all three units.
+
+Please refer to the charm configuration for full details on all HA config
+options.
+
+
+Use with a Load Balancing Proxy
+===============================
+
+Instead of deploying with the hacluster charm for load balancing, its possible
+to also deploy the dashboard with load balancing proxy such as HAProxy:
+
+    juju deploy haproxy
+    juju add-relation haproxy openstack-dashboard
+    juju add-unit -n 2 openstack-dashboard
+
+This option potentially provides better scale-out than using the charm in
+conjunction with the hacluster charm.

+
+    OpenStack Releases and template loading
+    ---------------------------------------
+    When the object is instantiated, it is associated with a specific OS
+    release.  This dictates how the template loader will be constructed.
+
+    The constructed loader attempts to load the template from several places
+    in the following order:
+        - from the most recent OS release-specific template dir (if one exists)
+        - the base templates_dir
+        - a template directory shipped in the charm with this helper file.
+
+
+    For the example above, '/tmp/templates' contains the following structure:
+        /tmp/templates/nova.conf
+        /tmp/templates/api-paste.ini
+        /tmp/templates/grizzly/api-paste.ini
+        /tmp/templates/havana/api-paste.ini
+
+    Since it was registered with the grizzly release, it first seraches
+    the grizzly directory for nova.conf, then the templates dir.
+
+    When writing api-paste.ini, it will find the template in the grizzly
+    directory.
+
+    If the object were created with folsom, it would fall back to the
+    base templates dir for its api-paste.ini template.
+
+    This system should help manage changes in config files through
+    openstack releases, allowing charms to fall back to the most recently
+    updated config template for a given release
+
+    The haproxy.conf, since it is not shipped in the templates dir, will
+    be loaded from the module directory's template directory, eg
+    $CHARM/hooks/charmhelpers/contrib/openstack/templates.  This allows
+    us to ship common templates (haproxy, apache) with the helpers.
+
+    Context generators
+    ---------------------------------------
+    Context generators are used to generate template contexts during hook
+    execution.  Doing so may require inspecting service relations, charm
+    config, etc.  When registered, a config file is associated with a list
+    of generators.  When a template is rendered and written, all context
+    generates are called in a chain to generate the context dictionary
+    passed to the jinja2 template. See context.py for more info.
