There's already info about assign(key, val) on the rspec-rails readme: http://github.com/rspec/rspec-rails. I'll add something about assigns(:key) as well.
Keep in mind that assign(k,v) is used in view specs to provide data to the view, whereas assigns(key) is used in controller specs to express expectations about what the controller does.
As for the wiki, let's hold off on that for now. There is currently insufficient documentation in too many places, and the wiki has, at times, caused more confusion than benefit. I've got a few thoughts rolling around about how to best address this, and I'll follow up on that in a separate thread in the next couple of days.
