   "description": "Philter is a JS plugin giving you the power to control CSS filters with HTML data attributes. Visit the [Demo page](http://specro.github.io/Philter/) for examples. ## Dependencies Philter comes in two flavors - jQuery and vanilla JS. Choose the one you want just don't forget in jQuery case to include it: ```HTML <script src=\"http://code.jquery.com/jquery-2.1.4.min.js\"></script> ``` You could also use Bower which is my preferred method. ## Installation Download the plugin and move the 'philter' directory to your 'js' directory, then include it in your page: ```HTML <script src=\"js/philter/philter.min.js\"></script> ``` or in jQuery ```HTML <script src=\"js/philter/jquery.philter.min.js\"></script> ``` And that's it! You're ready to go! ## How To First initiate the plugin: ```HTML <script>   new Philter(); </script> ``` or again in jQuery",
