Play integration documentation too basic

[ScalaWilliam]

Good day! Interesting project, this is and has some nice integrations!

As a newbie I'm looking at http://frees.io/docs/integrations/play/ and as a potential user, I am confused as to what I can do with this. The example of 'Noop' and sending out a static result is a fairly uncommon use case.

It would be nice if the Play integration example looked as comprehensive as that for http4s - http://frees.io/docs/integrations/http4s/
