How to set up a scrape with the scraped_resource gem?

I discovered the scraped_resource gem, which sounds like a great way to do screen scraping. How do you create a scraper using this gem? It's brand new, so I haven't been able to find any docs.

Thanks!

If you are new to web scraping and open to alternatives, then better to use an established library. In the ruby world scrubyt is popular.
