修改目录结构：

完成初始化 HUGO 后，生成默认的目录结构为：

my-site/
...
└── hugo.toml         <-- 站点配置文件

为了使目录看起来清爽一些，创建一个父文件夹 config 和一个子文件夹 _default 并把所有的配置文件放在该目录中:

my-site/
...
├── config/           <-- 站点配置文件
│   └── _default/
│       └── hugo.toml
...

站点配置文件

HUGO 完成初始化后默认创建的站点 hugo.toml 只有三行配置：

baseURL = 'https://example.org/'
languageCode = 'en-us'
title = 'My New Hugo Site'

后续对站点设置时会添加更多的配置项，以 PaperMod 主题的部分配置为例：

baseURL = 'https://example.org/'
languageCode = 'en-us'
title = 'My New Hugo Site'
theme = 'PaperMod'

enableEmoji = true

[markup]
  [markup.goldmark]
    [markup.goldmark.renderer]
      unsafe = true

[params]
DateFormat = '2006-01-02'

defaultTheme = 'auto'
# defaultTheme = 'light'
# defaultTheme = 'dark'

ShowWordCount = true
ShowReadingTime = true
ShowPostNavLinks = true
ShowCodeCopyButtons = true
ShowAllPagesInArchive = true

[params.profileMode]
    enabled = true

    title = "My New Hugo Site"
    subtitle = 'My New Hugo Site'
    imageUrl = ''

    [[params.profileMode.buttons]]
        name = 'Gallery'
        url = '/gallery/'

    [[params.socialIcons]]
        name = 'rss'
        url = 'index.xml'

[[menus.main]]
    identifier = "Posts"
    name = "Posts"
    url = "/posts/"
    weight = 20

[[menus.main]]
    identifier = "Archives"
    name = "Archives"
    url = "/archives/"
    weight = 30

[[menus.main]]
    identifier = "About"
    name = "About"
    url = "/about/"
    weight = 50

避免篇幅过长省略了大部分配置项，反正一大长串的配置文件本人是不想再看一眼了，因此需要按照配置关键字对这单个配置文件进行拆分成如下形式：

my-site/
└── config/
    └── _default/
        ├── hugo.toml
        ├── params.toml
        └── menus.toml

hugo.toml

baseURL = 'https://example.org/'
languageCode = 'en-us'
title = 'My New Hugo Site'
theme = 'PaperMod'

enableEmoji = true

[markup]
  [markup.goldmark]
    [markup.goldmark.renderer]
      unsafe = true

但也不要为了拆分而拆分， [markup] 是一个很好的例子。

params.toml

DateFormat = '2006-01-02'

defaultTheme = 'auto'
# defaultTheme = 'light'
# defaultTheme = 'dark'

ShowWordCount = true
ShowReadingTime = true
ShowPostNavLinks = true
ShowCodeCopyButtons = true
ShowAllPagesInArchive = true

[profileMode]
    enabled = true

    title = "My New Hugo Site"
    subtitle = 'My New Hugo Site'
    imageUrl = ''

    [[profileMode.buttons]]
        name = 'Gallery'
        url = '/gallery/'

    [[socialIcons]]
        name = 'rss'
        url = 'index.xml'

menus.toml

[[main]]
    identifier = "Posts"
    name = "Posts"
    url = "/posts/"
    weight = 20

[[main]]
    identifier = "Archives"
    name = "Archives"
    url = "/archives/"
    weight = 30

[[main]]
    identifier = "About"
    name = "About"
    url = "/about/"
    weight = 50
