《Github》 是做什么的？
GitHub是世界上最大的代码托管平台，超7千万开发者正在使用，为开发者提供Git仓库的托管服务。这是一个让开发者与朋友、同事、同学及陌生人共享代码的完美场所。
GitHub is where over 83 million developers shape the future of software, together. Contribute to the open source community, manage your Git repositories, review code like a pro, track bugs and features, power your CI/CD and DevOps workflows, and secure code before you commit it.
