+
+> A plugin of automatically generating clean urls
+
+## Install
+
+```bash
+yarn add -D @vuepress/plugin-clean-urls
+# OR npm install -D @vuepress/plugin-clean-urls
+```
+
+## Usage
+
+```javascript
+module.exports = {
+  plugins: ['@vuepress/clean-urls'] 
+}
+```
+
+## Options
+
+### normalSuffix
+
+- Type: `string`
+- Default: `''`
+
+The suffix for normal pages. For example, `foo/bar.md` will become:
+
+- `foo/bar.html` by default (without this plugin)
+- `foo/bar/` (with `normalSuffix` set to `'/'`)
+- `foo/bar` (with `normalSuffix` set to `''`)
+
+### indexSuffix
+
+- Type: `string`
+- Default: `'/'`
+
+The suffix for index pages. For example, `foo/index.md` will become:
+
+- `foo/` by default (without this plugin)
+- `foo` (with `indexSuffix` set to `''`)
+- `foo/index.html` (with `indexSuffix` set to `'/index.html'`)
+
+::: tip
+An index page is a page with a file name of index.md or readme.md (case insensitive).

+
+## 安装

+
+## 使用

+
+## 选项
+
+### normalSuffix
+
+- 类型: `string`
+- 默认值: `''`
+
+普通页面的链接后缀。举个例子，`foo/bar.md` 会自动变成：
+
+- `foo/bar.html` 在默认情况下（未安装本插件时）
+- `foo/bar/`（当 `normalSuffix` 被设为 `'/'` 时）
+- `foo/bar`（当 `normalSuffix` 被设为 `''` 时）
+
+### indexSuffix
+
+- 类型: `string`
+- 默认值: `'/'`
+
+索引页面的链接后缀。举个例子，`foo/index.md` 会自动变成：
+
+- `foo/` 在默认情况下（未安装本插件时）
+- `foo`（当 `indexSuffix` 被设为 `''` 时）
+- `foo/index.html`（当 `indexSuffix` 被设为 `'/index.html'` 时）
+
+::: tip
+索引页面是指文件名为 index.md 或者 readme.md 的页面（不区分大小写）。
