与集中式的版本管理工具不同, git采用分布式的版本管理方式. 由于最为广泛使用的git的仓库github只提供public的免费版本，所以更适合开源项目的管理，priavte仓库收费加之数据保留在远端的服务方式，很多企业需要创建供自己使用的github，功能非常类似的gitlab此时就能派上用场了。

warning: push.default is unset; its implicit value is changing in
Git 2.0 from ‘matching‘ to ‘simple‘. To squelch this message
and maintain the current behavior after the default changes, use:

  git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

  git config --global push.default simple

See ‘git help config‘ and search for ‘push.default‘ for further information.
(the ‘simple‘ mode was introduced in Git 1.7.11. Use the similar mode
‘current‘ instead of ‘simple‘ if you sometimes use older versions of Git)
