+Wox   [![Build status](https://ci.appveyor.com/api/projects/status/bfktntbivg32e103)](https://ci.appveyor.com/project/qianlifeng/wox)
+=========
+[Wox](http://www.getwox.com) is an effective launcher for windows, which was inspired by [Alfred](http://www.alfredapp.com/) and [Launchy](http://www.launchy.net/). Wox provide bundles of features let you access infomations quickly. 
+
+Features
+=========
+1. Search applications, files (via everything plugin) and chrome bookmarks
+2. Search web contents with shortcuts (e.g. search google with `g keyword` or `youtube keyword`)
+3. Search clipboard history (via clipboard plugin) 
+4. Themes support, get more themes from [http://www.getwox.com/theme](http://www.getwox.com/theme)
+5. Plugin support, get more plugins from [http://www.getwox.com/plugin](http://www.getwox.com/plugin)
+
+Screenshot
 =========

-This is Wox Dev branch. We will develop new feature here and merge to master when we want to release a new version.  
-**Please send pull request to this branch if you want to contribute codes**
