Git config

after installation, global setting and remote.

1, user name and email:

$ git config --global user.name "xxx"
$ git config --global user.email [e-mail]

2, create ssh key (in local PC):　　

$ ssh-keygen -t rsa -C "[e-mail]"

成功的话会在~/下生成.ssh文件夹，进去，打开id_rsa.pub，复制里面的key。

3, access the generated key, and add this ssh key to github account<SSH and GPG keys>:

4, test, remember to select "yes" 

$ ssh -T [e-mail]

如果是第一次的会提示是否continue，输入yes就会看到：You've successfully authenticated, but GitHub does not provide shell access 。这就表示已成功连上github。
