+
+A Hexo plugin that adds emoji support, using [Github Emojis API][ghemojis].
+
+Check out the [Emoji Cheat Sheet](http://www.webpagefx.com/tools/emoji-cheat-sheet/) for all the emojis it supports.
+
+## Installation
+
+``` bash
+$ npm install hexo-filter-github-emojis --save
+```
+
+## Options
+
+You can configure this plugin in `_config.yml`. Default options:
+
+``` yaml
+githubEmojis:
+  enable: true
+  className: github-emoji
+  localEmojis:
+```
+
+The filter will try to download the latest version of [Github Emojis][ghemojis] list. If the network is unavailable or too slow it will use the backup version.
+
+- **className** - Image class name. For `:sparkles:` the filter will generate something like this:
+
+  ```html
+  <img class="github-emoji" title=":sparkles:" alt=":sparkles:" src="https://assets-cdn.github.com/images/icons/emoji/unicode/2728.png" height="20" width="20">
+  ```
+
+- **localEmojis** - You can specify your own list. An object or JSON string is valid. The filter will first check the `localEmojis` then fallback to the [Github Emojis][ghemojis] list.
+
+  For example:
+  
+  ``` yaml
+  githubEmojis:
+    localEmojis:
+      arrow_left: https://path/tp/arrow_left.png
+      arrow_right: https://path/tp/arrow_right.png
+  ```
+
+[ghemojis]: https://api.github.com/emojis
