-tags-input
-==========
+## A fork of [tags-input](https://github.com/developit/tags-input)
 
-[![NPM Version](http://img.shields.io/npm/v/tags-input.svg?style=flat)](https://www.npmjs.org/package/tags-input)

-[![Gitter Room](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/developit/tags-input)
+Slowly refactoring this module to add:
 
-**Features:**
+ - Plain CommonJS  / ES2017 / SASS and eslint.
+ - Unminified variables, code run through [prettier](https://github.com/prettier/prettier-eslint-cli).
+ - Unit tests
 
-- I said `<input type="tags">` should be a thing.
-- With full keyboard, mouse and focus support.
-- Works with HTML5 `pattern` and `placeholder` attributes, too!
-- Native [`change`](https://developer.mozilla.org/en-US/docs/Web/Events/change) and [`input`](https://developer.mozilla.org/en-US/docs/Web/Events/input) _("live" change)_ events.
-- Using [preact](https://github.com/developit/preact)? (or react?) There's a wrapper called [preact-token-input](https://github.com/developit/preact-token-input)
-- Works in modern browsers and IE10+

-Examples

-It's easy to use! In addition to the example code, you'll also need to
-include `tags-input.css` - I didn't bundle it because that's a bit gross.
