+## About Iceman fork/repo
+
+The [Iceman fork/repo](https://github.com/RfidResearchGroup/proxmark3) has more powerful functions like offline sniff. These guys even developed a new hardware called Proxmark3 RDV4 with smart card support. But the official repo and the Iceman repo is not fully compatible.  
+This GUI was designed for only official repo at first, but I'm trying to make it compatible with Iceman repo.

+## About Compiled Windows clients
+
+A cool guy [Gator96100](https://github.com/Gator96100) creates [ProxSpace](https://github.com/Gator96100/ProxSpace) and makes it possible to compile both the firmware and client on Windows.  
+Also, he makes the [pre-compiled Windows client](http://www.proxmark.org/forum/viewtopic.php?id=3975) so you can download it and run your PM3 client on Windows instantly.  
+I included his compiled client in my releases so you can use the GUI on the fly, and you can also use the GUI with your prefered client.  
+Great thanks to him.

 ## Update Log:
 
+### V0.1.2

++ Make UI Customizable
++ Save client path automatically
++ Add Trailer Decoder

+ ## 关于冰人版
+ 这个GUI一开始是针对官方版本做的，现在正在尽力让它兼容冰人版的功能

+## 关于预编译Windows客户端
+
+一个国外大佬 [Gator96100](https://github.com/Gator96100) 做了个 [ProxSpace](https://github.com/Gator96100/ProxSpace) 以便在Windows平台上编译PM3固件和客户端，他还把自己编译好的客户端放到了[论坛](http://www.proxmark.org/forum/viewtopic.php?id=3975)里面  
+文件都是放到Google Drive上面的，国内网络无法访问，所以我在release版本里面放了个带预编译客户端版本的GUI。这个GUI也可以搭配你自己的客户端使用  
+(本来打算在CSDN下载里面放几个最新版客户端的，结果不能把下载币改为0)  
+感谢大佬
