 CodeSignBreak
 =============
-This is a tool that patches Xcode and your projects in order to let you install your apps on your `jailbreak` device with `appsync` like [JailCoder](http://oneiros.altervista.org/jailcoder/) which not updates now(on 10.10 and Xcode6 crashed).

+=============
+This is a tool that patches Xcode6(-) and your projects in order to let you install your apps on your `jailbreak` device with `appsync` like [JailCoder](http://oneiros.altervista.org/jailcoder/) which not updates now(on 10.10 and Xcode6 crashed).
 
+As to Xcode7(+), there are no need to hack Xcode and projects to debug on devices. Just create your free Signing Identities in Xcode--Preference--Accounts--AppleIDs--View Details and fix the warning.

+CodeSignBreak
+=============
+由于[JailCoder](http://oneiros.altervista.org/jailcoder/)没有更新且在10.10下崩溃，所以仿照它自己写了一个iOS免证书真机调试的工具，主要功能是自动给Xcode6(-)和项目文件打补丁。请保证iOS设备已越狱并安装有`appsync`。
+
+Xcode7(+)官方允许真机调试了,不得不说是个好消息.

+
+# 要求
+## 电脑上
+有两种安装Xcode的方法：
+
+1. 下载dmg并拖拽到 `/Applications`.
+
+2. 从Appstore里直接安装.
+第2种方法安装的Xcode权限是`root:wheel`, 而第1种安装的权限`login user:admin`. 无论哪种，iPhoneSimulator动态库文件 'dyld_sim'必须是`root`:
+> Detail: ` find . -user root -print`
+> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/dyld_sim
+> /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/share/man/whatis
+> /Applications/Xcode.app/Contents/Developer/usr/share/man/whatis
+由于在程序里面提权并不好，所以，如果你是使用第二种方式安装的话，请使用下面的命令改变文件拥有组为`admin`:
+ ```zsh
+sudo chgrp -R admin /Applications/Xcode.app 
+ ```
+## 设备上
+
+1. Jailbreak
+
+2. [appsync(不要通过PP助手安装)](https://github.com/angelXwind/AppSync)
+
+# 已测试
