 ### Read models
 
-Read models live at the application level. In our case it's in the Rails app:
+Read models are application specific so they live at the application level.

 This project has several high-level goals:
 
-- to show that it's possible to modularize a non-trivial Rails app
-- to serve as an example of a DDD project (not only in Rails)
-- to let people play with this codebase to get a feel if DDD is for them
-- to show that tests can be fast if the app is well modularized
-- to show a proper pyramid of tests
-- to teach event-driven architectures
-- to show how to use RailsEventStore
-- to bring DDD enthusiasts from .Net/Java/PHP/others to the Ruby world 😎
-- to popularize professional testing techniques - mutation testing
-- to allow programmers to reuse existing and popular domains
