INTRODUCTION

------------

Add jQuery Waypoints plugin to the site.

REQUIREMENTS

------------

Use composer to install module,

then it will install levmyshkin/waypoints automatically.

INSTALLATION

------------

* Install as you would normally install a contributed Drupal module. Visit

  https://www.drupal.org/node/1897420 for further information.

If you install modules manually (without composer),

then you will need to put waypoints library from here:

https://github.com/levmyshkin/waypoints

So jquery.waypoints.min.js file will be placed in:

/libraries/waypoints/lib/jquery.waypoints.min.js

CONFIGURATION

-------------

Open the module configuration form:

/admin/config/user-interface/waypoints

And enable checkbox "Always include JavaScript file to the site"

Usage example:

```

(function ($) {

  $(document).ready(function(){

    if ($('#block-1').length ) {

      var waypoint = new Waypoint({

        element: document.getElementById('block-1'),

        handler: function(direction) {

          $('.another-block')

            .toggleClass('someclass', direction === 'down');

        }

      });

    }

  });

}(jQuery));

```
