+Dev setup instructions
+----------------------
+install the development dependencies nodejs, npm, grunt and bower
+from the top level directory run the following commands
+  * npm install
+  * bower install
+
+The timeline server (ATS) url by default points to http://localhost:8188. This can be
+changed to point to another host by editing the App.AtsBaseUrl entry in the
+app/scripts/app.js file.
+
+For development run 'grunt serve'. This runs a dev server on port 9000. 
+navigate to http://localhost:9000 if a browser does not open automatically.
+Any changes made will be live-reloaded on the browser.
+
+For creating a distribution version, run 'grunt build'. The distributable 
+version will be placed under the dist directory.
