Setting up an A/B test is really simple.

Once you have logged into your account, you can either a create a new project or edit a draft project, then add tasks to the project. For each task you can choose either a single test or an A/B test. Select A/B test, upload or select your screenshots and you are ready to go.

A/B testing is a great way to compare alternative designs, old and new designs, and a range of other interfaces. Check out our screencast for more suggestions.
