+      <p>
+        We provided this environment to help you creating a custom view.
+      </p>
+      <p>
+        When the environment is running you will have an
+        <code>auto-reload</code>
+        feature enabled, so any time you update one of your files, the browser will be reloaded.
+      </p>
+      <p> <i>Note that is environment is already functional and that it is loading information from the XOS APIs and presenting them using the
+          <code>xos-table</code>
+          component.</i> 
+      </p>
+      <h3>Development notes:</h3>
+      <p>
+        This views are designed using
+        <a href="https://angularjs.org/" target="_blank">Angular Js</a>
+        version 1.4.7 and
+        <a href="http://getbootstrap.com/" target="_blank">Bootstrap</a>
+        3.3.6 is included.
+      </p>
+      <p>
+        We just want to remind you that this development environment provide you three helper command:
+        <ul>
+          <li>
+            <code>npm start</code>
+            - will start your setup (you should already be familiar with it)
+          </li>
+          <li>
+            <code>npm test</code>
+            - will execute your unit tests defined with
+            <a href="https://karma-runner.github.io/0.13/index.html" target="_blank">Karma</a>
+            and
+            <a href="jasmine.github.io" target="_blank">Jasmine</a>
+            . You can check the
+            <code>spec/</code>
+            folder to see an example of your first test.
+          </li>
+          <li>
+            <code>npm run build</code>
+            - will build your dashboard and make it available to XOS
+          </li>
+        </ul>
+      </p>
+      <h3>Helpers:</h3>
+      <p>
+        We provide a set of helpers that you can leverage in your dashboard:

  * *admin-openrc.sh*: Admin credentials for your OpenStack cloud
  * *id_rsa[.pub]*: A keypair that will be used by the various services
  * *node_key*: A private key that allows root login to the compute nodes
 
-They will have been put there for you by the cluster installation scripts.
+XOS can then be brought up for CORD by running a few `make` commands.
+First, run:
 
-**If your setup uses the CORD fabric**, you need to modify the autogenerated VTN
-configuration and node tags, and edit `cord-vtn-vsg.yml` as follows.
-
- 1. The VTN app configuration is autogenerated by XOS.  For more information
-about the configuration, see [this page on the ONOS Wiki](https://wiki.onosproject.org/display/ONOS/CORD+VTN),
-under the **ONOS Settings** heading.  To see the generated
-configuration, go to http://xos/admin/onos/onosapp/, click on
-*VTN_ONOS_app*, then the *Attributes* tab, and look for the
-`rest_onos/v1/network/configuration/` attribute.  You can edit this
-configuration after deleting the `autogenerate` attribute (otherwise XOS will
-overwrite your changes), or you can change the other
-attributes and delete  `rest_onos/v1/network/configuration/` in order
-to get XOS to regenerate it.
-
- 2. The process of autoconfiguring VTN also assigns some default values to per-node parameters.  Go to
- http://xos/admin/core/node/, select a node, then select the *Tags* tab.  Configure the following:
-  * `bridgeId` (the ID to set on the node's br-int)
-  * `dataPlaneIntf` (the data plane interface for the fabric on the node)
-  * `dataPlaneIp` (the IP address for the node on the fabric)
-
- 3. Modify `cord-vtn-vsg.yml` and set these parameters to the
-appropriate values for the fabric:
-  * `addresses_vsg:properties:addresses` (IP address block of fabric)
-  * `addresses_vsg:properties:gateway_ip` 
-  * `addresses_vsg:properties:gateway_mac` 
-
-If you're not using the fabric then the default values should be OK.  
-
-XOS can then be brought up for CORD by running a few `make` commands:
 ```
 ubuntu@xos:~/xos/xos/configurations/cord-pod$ make
+```
+
+After this you will be able to login to the XOS GUI at
+*http://xos/* using username/password `padmin@vicci.org/letmein`.
+Before proceeding, you should verify that objects in XOS are
+being sync'ed with OpenStack.  Log into the GUI and select *Users*
+at left.  Make sure there is a green check next to `padmin@vicci.org`.
+
+> If you are **not** building the single-node development POD, the next
+> step is to create and edit the VTN configuration.  Run `make vtn-external.yaml`
+> then edit the `vtn-external.yml` TOSCA file.  The `rest_hostname:`
+> field points to the host where ONOS should run the VTN app.  The
+> fields in the `service_vtn` and the objects of type `tosca.nodes.Tag`
+> correspond to the VTN fields listed
+> on [the CORD VTN page on the ONOS Wiki](https://wiki.onosproject.org/display/ONOS/CORD+VTN),
+> under the **ONOS Settings** heading; refer there for the fields'
+> meanings.  
+
+Then run:
+
+```
 ubuntu@xos:~/xos/xos/configurations/cord-pod$ make vtn
+```
+The above step configures the ONOS VTN app by generating a configuration
+and pushing it to ONOS.  You are able to see and modify the configuration
+via the GUI as follows:
+
+* To see the generated configuration, go to *http://xos/admin/onos/onosapp/*, select
+*VTN_ONOS_app*, then the *Attributes* tab, and look for the
+`rest_onos/v1/network/configuration/` attribute.  
+
+* To change the VTN configuration, modify the fields of the VTN Service object
+and the Tag objects associated with Nodes.  Don't forget to select *Save*.
+
+* After modifying the above fields, delete the `rest_onos/v1/network/configuration/` attribute
+in the *ONOS_VTN_app* and select *Save*.  The attribute will be regenerated using the new information.
+
+* Alternatively, if you want to load your own VTN configuration manually, you can delete the
+`autogenerate` attribute from the *ONOS_VTN_app*, edit the configuration in the
+`rest_onos/v1/network/configuration/` attribute, and select *Save*.
+
+Before proceeding, check that the VTN app is controlling Open vSwitch on the compute nodes.  Log
+into ONOS and run the `cordvtn-nodes` command:
+
+```
+$ ssh -p 8101 karaf@onos-cord   # password is karaf
+onos> cordvtn-nodes
+hostname=nova-compute, hostMgmtIp=192.168.122.177/24, dpIp=192.168.199.1/24, br-int=of:0000000000000001, dpIntf=veth1, init=COMPLETE
+Total 1 nodes
+```
+The important part is the `init=COMPLETE` at the end.  If you do not see this, refer to
+[the CORD VTN page on the ONOS Wiki](https://wiki.onosproject.org/display/ONOS/CORD+VTN) for
+help fixing the problem.  This must be working to bring up VMs on the POD.
+
+> If you are **not** building the single-node development POD, modify `cord-vtn-vsg.yml` 
+> and change `addresses_vsg` so that it contains the IP address block,
+> gateway IP, and gateway MAC of the CORD fabric.  
+
+Then run:
+
+```
 ubuntu@xos:~/xos/xos/configurations/cord-pod$ make cord
 ```
 
-After the first 'make' command above, you will be able to login to XOS at
-*http://xos/* using username/password `padmin@vicci.org/letmein`.

+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array of at least `200` elements
+     * and any iteratees accept only one argument. The heuristic for whether a
+     * section qualifies for shortcut fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.
+     *
+     * In addition to lodash methods, wrappers have `Array` and `String` methods.
+     *
+     * The wrapper `Array` methods are:
+     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+     *
+     * The wrapper `String` methods are:
+     * `replace` and `split`
+     *

+     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
+     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+     *
