Why using Intro.js?

When new users visit your website or product you should demonstrate your product features using a step-by-step guide. Even when you develop and add a new feature to your product, you should be able to represent them to your users using a user-friendly solution. Intro.js is developed to enable web and mobile developers to create a step-by-step introduction easily.

Intro.js is open-source and free to use. Share the project with your friends.

Add progress-bar to your step-by-step introduction. It's as easy as adding showProgress option to your Intro.js instance (e.g. introJs().setOption('showProgress', true).start();)

Hints are the new feature in Intro.js that enables you to add additional descriptions to any part of a web page. You can define hints by adding data-hint attribute to the HTML elements.
