Cucumber_rails' old-school web-steps have been deprecated for a while, urging developers to write high-level step definitions that directly use Capybara or Webrat.
We think that's a bit drastic. More high-level steps are good, but ticking the odd check box with a general step is not always bad.
If you want to migrate an existing cucumber suite, check out the migration guide.
You can find a list of all supplied steps in the readme on github.
