 This app demonstrates how to bootstrap JSON data from ERB templates into a
 Backbone app.
 
-## Set up
+This is done by dumping JSON into a `<script>` tag on `posts/index.html.erb`,
+then loading the data into a Backbone collection to be rendered by a Backbone
+view.
 
-    $ bundle
+## Reasoning
 
-## Tests
+Bootstrapping data to the view and using Backbone to display it is a quick way
+of integrating Backbone into an app that currently doesn't use it. Why?
+Because it requires no change from the controllers to expose an API. By
+reading JSON from the page, it becomes very simple to use pieces of Backbone
+(models, collections, views) without AJAX requests or routers; those can come
+later.
