simple form

Hi, I quite a newbie to rails and ruby and have followed the tutorial on http://railstutorial.org and have sucessfully completed it and have sign up up and running but now i want to implement a form on one of the pages and im completly lost and cant figure out how to do it. Can anyone help?

There's a guide on form helpers: http://guides.rubyonrails.org/form_helpers.html
