 ### What is Angelo?
 
 Just like Sinatra, Angelo gives you an expressive DSL for creating web applications. There are some
 notable differences, but the basics remain the same: you can either create a "classic" application
 by requiring 'angelo/main' and using the DSL at the top level of your script, or a "modular"
 application by requiring 'angelo', subclassing `Angelo::Base`, and calling `.run!` on that class for the
 service to start.

+In addition, and perhaps more importantly, **Angelo is built on Reel, which is built on
 Celluloid::IO and gives you a reactor with evented IO in Ruby!**
 
 Things will feel very familiar to anyone experienced with Sinatra. You can define
 route handlers denoted by HTTP verb and path with parameters set from path matching (using
 [Mustermann](#mustermann)), the query string, and post body.

+### JSON HTTP API
+
+If you post JSON data with a JSON Content-Type, angelo will:
+
+* merge objects into the `params` SymHash
+* parse arrays and make them available via `request_body`
+
+N.B. `request_body` is functionally equivalent to `request.body.to_s` otherwise.
+
+If your `content_type` is set to `:json`, angelo will convert:
+
+* anything returned from a route block that `respond_to? :to_json`
+* `RequestError` message data
+* `halt` data

+### Name
+
+Why the name "Angelo"? Since the project mimics Sinatra's DSL, I thought it best to keep a reference to
+The Chairman in the name. It turns out that Frank Sinatra won an Academy Award for his role 'Angelo
+Maggio' in 'From Here to Eternity'. I appropriated the name since this is like Sinatra on Reel (film).
