+AngularJS Emoji Picker is a simple AngularJs module which allows you to add emoji images to your model value. This project is heavily inspired by
+[Angular Emoji](https://github.com/Coraza/angular-emoji-popup/), but it doesn't require external dependencies like JQuery, JQuery plugins and so forth.

 Usage

-
 ```javascript
 angular.module('myModule', ['vkEmojiPicker']);
 ```
+By default Emoji Picker uses its own popover, which, to be honest, has not a very great realization. But you have an option - you can use
+external dependencies: [Angular Strap](https://github.com/mgcrea/angular-strap) and [Bootstrap](https://github.com/twbs/bootstrap). In that
+case you have to include additional scripts on your page:
+
+```html
+<link rel="stylesheet" href="/path/to/bootstrap/dist/css/bootstrap.min.css">
+<script src="/path/to/angular-strap/dist/angular-strap.min.js"></script>
+<script src="/path/to/angular-strap/dist/angular-strap.tpl.min.js"></script>
+```
+
+```javascript
+angular.module('myModule', ['vkEmojiPicker', 'mgcrea.ngStrap']);
+```
+
+Also Emoji Picker provides a couple handy directives:
+
+* `emojify` - converts an emoji string into image
+
+`<div ng-bind-html="message | emojify"></div>`
+
+* `hexify` - converts an emoji string into UTF-8 characters
+
+`<div ng-bind-html="message | hexify"></div>`
+
 
 Known issues and limitations

-1. **It's not ready for production yet**
-2. The picker requires AngularJS 1.3. Didn't test on 1.4 version, probably it's broken.

 Also consider running any code through the code style checker `jscs` (or even better use it in your editor) with preset set to `yandex`,
 but the parameter `validateIndentation` should be changed to a value `2` instead of original one `4`
