I am working through the CRUD section in Chapter 4 There doesn't seem to be any instruction on configuring the routing.yml file.

I changed the default rule

homepage:
url: /
param: { module: addressbook, action: index }

that let me bring up the index page, but the 'new' hyperlink returns a 404..
I read up to this point thoroughly, where did I miss the instructions to configure the routing.yml?
(is there more than was described in the hello world demo?)

/update/
I figured out that you have to use http://localhost/frontend_dev.php

I still wish the routing.yml configuration was explained a little better. There is not much on it.
