It's an outlining software - though, technically, it could take you all the way to a formatted script - but that's not what it's really about.
There's a free download with full functionality but limited save (10 pages) - but enough to see if you like it.
There's used to be a program called "StoryView " which I absolutely loved - but is no longer supported.
This is like that but on steroids.
And theres' a ton of tutorial videos out there.
Enjoy.
