Devise: Can someone write a document about how devise work?

[1c7]

where all these code?
by default, the devise controller and devise view code doesn't exist in Rails project folder,
so must be somewhere else, but where?

and why write stuff like this in routes.rb and it work?

devise_for :users, skip: [:sessions, :registrations]

I would like to see a tutorial that explain how devise work in bigger picture.
Thanks :smile:

Devise is an engine, so that stuff is hidden in the gem.
More on Engines: http://guides.rubyonrails.org/engines.html

More on how to generate views into your application to modify:

More on how the routes work that:
