No more info about dynamic_form in rails guides?

I remember for sure there was a explanation with screenshots about dynamic_form in Rails Guides. Now I cannot find it, neither in Edge nor in standard guide. Have they removed it? Why? Where may I find the info again?

dynamic_form was included in Rails2 but stripped out of Rails3 (and 4). It’s now available as a gem.
