Better introductions for websites and features with a step-by-step guide for your projects.
Intro.js can be added to your site in three simple steps:
1) Include intro.js
and introjs.css
(or the minified version for production) in your page.
2) Add data-intro
and data-step
to your HTML elements.
For example:
<a href='http://google.com/' data-intro='Hello step one!' data-step='1'></a>
See all attributes here.

introJs().start();
Optionally, pass one parameter to introJs
function to limit the presentation section.
