The docs directory will automatically generate the corresponding left menu directory according to the nested association of the file name and the folder
eg:
.
├── 1_api-examples.md
├── 2_markdown-examples.md
└── 3_hello
└── aa.md
The static directory of the corresponding site is as follows:
.
├── api-examples.md
├── markdown-examples.md
└── hello
└── aa.md
