+#标题
+第一篇笔记
+
+## 1.下载GIT
+
+- 下载地址：https://git-scm.com/downloads
+- 选择适合自己操作系统的版本进行下载安装。
+
+## 2.配置SSH    
+``` 
+ssh-keygen -t rsa -C "your_email@example.com"
+```
+- 输入命令后，会出现一系列提示，按回车键即可。
+- 之后会在用户目录下生成.ssh文件夹，里面有两个文件：id_rsa和id_rsa.pub。
+- 将id_rsa.pub的内容复制到GitHub的SSH Key中。
+
+## 3.创建仓库
+- 登录GitHub，点击右上角的“+”，选择“New repository”创建仓库。
+- 输入仓库名称，描述，选择公开或私有，点击“Create repository”创建。
+- 复制仓库的HTTPS地址，在本地命令行下执行：
+```
+git clone https://github.com/your_username/your_repository.git
+```
+- 克隆到本地后，在仓库目录下执行：
+```
+git status
+```
+- 显示当前仓库的状态。
+- 在仓库目录下执行：
+```
+git add .
+```
+- 添加所有文件到暂存区。
+- 在仓库目录下执行：
+```
+git commit -m "first commit"
+```
+- 提交暂存区到仓库。
+- 在仓库目录下执行：
+```
+git push -u origin master
+```
+- 推送本地仓库到远程仓库。
+
+## 4.创建README.md
+- 在仓库目录下创建一个README.md文件，内容随便写。
+- 在仓库目录下执行：
+```
+git add .
+```
+- 添加README.md文件到暂存区。
+- 在仓库目录下执行：
+```
+git commit -m "add README.md"
+```
+- 提交README.md文件到仓库。
+- 在仓库目录下执行：
+```
+git push -u origin master
+```
+- 推送README.md文件到远程仓库。
+
+## 5.创建分支
+- 在仓库目录下执行：
+```
+git branch new_branch
+```
+- 创建一个名为new_branch的分支。    
+- 在仓库目录下执行：
+```
+git checkout new_branch
+```
+- 切换到new_branch分支。
+- 在new_branch分支下修改文件，并提交到仓库。
+- 在仓库目录下执行：
+```
+git checkout master
+```
+- 切换回master分支。
+- 在master分支下执行：
+```
+git merge new_branch
+```
+- 将new_branch分支合并到master分支。
+- 在仓库目录下执行：
+```
+git push origin master
