这里我就只说说从安装到连接到github库时出现的错误，以及如何解决
1. 下载github,安装后你就可以在系统中右键看到 Gui 和 Bush按钮
2. 此时你可能会去尝试着去连接你在github中新建的工程,clone一下。可能会报错：github Permission denied (publickey)

Permission denied (publickey).
这里贴上安装之后需要执行的命令：https://help.github.com/articles/create-a-repo大家也可以直接按照这内容傻瓜式操作。(如访问不了,就去你的host文件里添加：
#github
207.97.227.239 github.com
65.74.177.129 www.github.com
207.97.227.252 nodeload.github.com
207.97.227.243 raw.github.com
204.232.175.78 documentcloud.github.com
204.232.175.78 pages.github.com
)
3. 原因在于本地文件中没有在github注册的ssh协议----publickey值
在这里Windows for Github提供了一键式帮助。大家可以参考：http://www.cnblogs.com/hielvis/archive/2012/06/05/2535495.html
我首先并没有参照那博主的步骤去解决，而是手动去生成publickey。
先去https://help.github.com/articles/error-permission-denied-publickey看看，里面针对github Permission denied (publickey)报错提供了解决方案
主要思路： 1. 先连接git@github.com，如果报错就添加一个publickey值
2. 此时添加的publickey值是不能用的，那就要自己去注册一个
3. 使用ssh-keygen -lf ~/.ssh/id_rsa.pub命令来创建一个id_rsa文件，具体位置如下(WIn XP下)：
4. 然后打开它,将内容复制到：https://github.com/settings/ssh -> Add SSH KEY.
最后重复刚开始的操作就OK了,可以连接到自己创建的库
往下就不帖命令了，大家可在Github官网中找到现成的
