To get a useful Data-Driven Estimate you need to have historical task data for a stable team. A "stable team" means there has been no significant change to the team or how they work.
Your data must be in CSV format and contain two columns "Started" and "Done" and a minimum of 15 tasks. Here is a sample file.
Next select the number of future tasks/stories and click "Estimate". You'll see a range of risky and safe delivery dates for your project.
