// ### WHAT?
//
// We will track anonymous usage of how you use storybook.
// We don't want any personal information.
// We just need to collect following information
//
//  * How many time a user runs start-storybook a day
//
// We will send a ping to our server when you run storybook with above information.

// ### WHY?
//
// We are maintaining React Storybook and we want to improve it.
// We also working on storybooks.io which is storybook related service.
// In order to get a real picture about the storybook usage,
// we need to get some real usage stats, not the amount of NPM downloads.
// This is why we do this.

// ### CAN I STOP THIS?
//
// You(or your company) may have certain policies.
// If so, you can stop sending these metrics.
// To do that, use --dont-track flag when running React Storybook.
//    start-storybook --dont-track -p 9001

// ### HELP US?
//
// Maintaining a open source project is hard.
// It's even harder for a startup like us (Kadira)
// Help us to make storybook better by sending these few metrics.
// Based on these metrics, we could improve storybook and build a profitable
// service around it. With that, we could continue to maintain and
// improve Storybook.
