Reference links
important points to explain

• Following problems
  
  git centralized to distributed management system

ssh keys to generate. And the id_rsa.pub added github.com in (this process is only to establish a channel can exchange visits only)

Just build a warehouse can exchange visits between github

Which in the end is to plant local user database push to end git.

Depending on your local user.email to identify the mailbox, in the user.email and git user name is one to one.

If user.email already registered in the git, email corresponding git user name is displayed.

If user.email in the absence of registration, is displayed user.name (in gray)

• Modify the mailbox to find after an arbitrary value can be seen commit author has changed
