# 什么是 GitHub？

GitHub 是用于版本控制和协作的代码托管平台。它可以让你和其他人在任何地方协同工作。

本教程讲解一些 GitHub 基本知识，如\_仓库\_，*分支*，*提交\_和\_拉取请求*。你将创建自己的 Hello World 仓库并学习 GitHub 的拉取请求工作流，这是一种流行的创建和审查代码的方法。

**无需写代码**

要完成本教程，你需要一个 [GitHub 帐户](https://github.com/) 和互联网。你不需要知道如何写代码，如何使用命令行或安装 Git（GitHub 正是基于这个版本控制软件开发）。

> **提示**：在单独的浏览器窗口（或标签页）中打开本指南，以便可以一边看本教程一边实践。
