Topic: Textile Editor Helper or equivalent

I am somewhat new to Rails, only really dabbled on and off in spare time over a couple of years.

I am currently on a concerted effort to get better at using rails and I am working on an app that requires user input, I have installed RedCloth and have been trying for a while to get the Textile Editor Helper, and some equivalents working in my Rails 3.1 app.

I was wondering if someone could go over the steps to accomplish this or point me in the direction of a good tutorial.

Many thanks.
