使用如下过程为GitHub中的项目创建好看的目录结构

1. 在Mac中使用如下命令安装tree工具：

# 安装 tree
brew install tree

2. 安装完成之后，在项目所在的目录中可以选择使用如下的命令输出项目结构：

# 使用-L参数指定遍历层级
tree -L 2
# 将目录的结构树导出到文件README.md
tree -L 2 >README.md
# 在结构中只显示文件夹
tree -d 
# 过滤不想要显示的文件或者文件夹，比如要过滤项目中的target文件夹；
tree -I pattern 
tree -I “target”
# 解决中文文件名乱码问题
tree -N

3. 具体的命令参数如下：
