devise forgot password setup - ruby-on-rails

Question

I am really new to rails and have been trying to work on building an application. I recently have installed devise and omniauth for facebook with great success after some time. When I was reading into devise, I noticed that Devise has a "forgot password" module built into it.
I have scoured the internet and for the life of me haven't figured out how to set it up. Is there any guide?I have been working for hours, but I haven't really had any results. How do I set this up? I am using rails 4.0 and the newest version of devise.
Thanks,

Devise consists of 10 modules and the one you're looking for is recoverable. In your devise model, you need to add :recoverable attribute for devise.
