+# Config Reference
+
+## Basic Config
+
+### base
+
+- Type: `string`
+- Default: `/`
+
+The base URL the site will be deployed at. You will need to set this if you plan to deploy your site under a sub path, for example GitHub pages. If you plan to deploy your site to `https://foo.github.io/bar/`, then `base` should be set to `"/bar/"`. It should always start and end with a slash.
+
+The `base` is automatically prepended to all the URLs that start with `/` in other options, so you only need to specify it once.
+
+**Also see:**
+
+- [Base URL](../guide/assets.md#base-url)
+- [Deploy Guide > Github Pages](../guide/deploy.md#github-pages)
+
+### title
+
+- Type: `string`
+- Default: `undefined`
+
+Title for the site. This will be the prefix for all page titles, and displayed in the navbar in the default theme.
+
+### description
+
+- Type: `string`
+- Default: `undefined`
+
+Description for the site. This will be rendered as a `<meta>` tag in the page HTML.
+
+### head
+
+- Type: `Array`
+- Default: `[]`
+
+Extra tags to be injected to the page HTML `<head>`. Each tag can be specified in the form of `[tagName, { attrName: attrValue }, innerHTML?]`. For example, to add a custom favicon:
+
+``` js
+module.exports = {
+  head: [
+    ['link', { rel: 'icon', href: `/logo.png` }]
+  ]
+}
+```
+
+### host
+
+- Type: `string`
+- Default: `'0.0.0.0'`
+
+Specify the host to use for the dev server.
+
+### port
+
+- Type: `number`
+- Default: `8080`
+
+Specify the port to use for the dev server.
+
+### dest
+
+- Type: `string`
+- Default: `.vuepress/dist`
+
+Specify the output directory for `vuepress build`.
+
+### ga
+
+- Type: `string`
+- Default: `undefined`
+
+Provide the Google Analytics ID to enable integration.
+
+### serviceWorker
+
+- Type: `boolean`
+- Default: `false`
+
+If set to `true`, VuePress will automatically generate and register a service worker that caches the content for offline use (only enabled in production).
+
+If developing a custom theme, the `Layout.vue` component will also be emitting the following events:
+
+- `sw-ready`
+- `sw-cached`
+- `sw-updated`
+- `sw-offline`
+- `sw-error`
+
+::: tip PWA NOTES
+The `serviceWorker` option only handles the service worker. To make your site fully PWA-compliant, you will need to provide the Web App Manifest and icons in `.vuepress/public`. For more details, see [MDN docs about the Web App Manifest](https://developer.mozilla.org/en-US/docs/Web/Manifest).
+
+Also, only enable this if you are able to deploy your site with SSL, since service worker can only be registered under HTTPs URLs.
+:::
+
+### locales
+
+- Type: `{ [path: string]: Object }`
+- Default: `undefined`
+
+Specify locales for i18n support. For more details, see the guide on [Internationalization](../guide/i18n.md).
+
+## Theming
+
+### theme
+
+- Type: `string`
+- Default: `undefined`
+
+Specify this to use a custom theme. With the value of `"foo"`, VuePress will attempt to load the theme component at `node_modules/vuepress-theme-foo/Layout.vue`.
+
+### themeConfig
+
+- Type: `Object`
+- Default: `{}`
+
+Provide config options to the used theme. The options will vary depending on the theme you are using.
+
+**Also see:**
+
+- [Default Theme Configuration](../default-theme-config/).
+
+## Markdown
+
+### markdown.slugify
+
+- Type: `Function`
+- Default: [source](https://github.com/vuejs/vuepress/blob/master/lib/markdown/slugify.js)
+
+Function for transforming header texts into slugs. This affects the ids/links generated for header anchors, table of contents and sidebar links.
+
+### markdown.anchor
+
+- Type: `Object`
+- Default: `{ permalink: true, permalinkBefore: true, permalinkSymbol: '#' }`
+
+Options for [markdown-it-anchor](https://github.com/valeriangalliat/markdown-it-anchor). (Note: prefer `markdown.slugify` if you want to customize header ids.)
+
+### markdown.toc
+
+- Type: `Object`
+- Default: `{ includeLevel: [2, 3] }`
+
+Options for [markdown-it-table-of-contents](https://github.com/Oktavilla/markdown-it-table-of-contents). (Note: prefer `markdown.slugify` if you want to customize header ids.)
+
+### markdown.config
+
+- Type: `Function`
+- Default: `undefined`
+
+A function to apply additional plugins to the [markdown-it](https://github.com/markdown-it/markdown-it) instance used to render source files. Example:
+
+``` js
+module.exports = {
+  markdown: {
+    config: md => {
+      md.use(require('markdown-it-xxx'))
+    }
+  }
+}
+```
+
+## Build Pipeline
+
+### postcss
+
+- Type: `Object`
+- Default: `{ plugins: [require('autoprefixer')] }`
+
+Options for [postcss-loader](https://github.com/postcss/postcss-loader). Note specifying this value will overwrite autoprefixer and you will need to include it yourself.
+
+### configureWebpack
+
+- Type: `Object | Function`
+- Default: `undefined`
+
+Modify the internal webpack config. If the value is an Object, it will be merged into the final config using [webpack-merge](https://github.com/survivejs/webpack-merge); If the value is a function, it will receive the config as the 1st argument and an `isServer` flag as the 2nd argument. You can either mutate the config directly, or return an object to be merged:
+
+``` js
+module.exports = {
+  configureWebpack: (config, isServer) => {
+    if (!isServer) {
+      // mutate the config for client
+    }
+  }
+}
+```
+
+### chainWebpack
+
+- Type: `Function`
+- Default: `undefined`
+
+Modify the internal webpack config with [webpack-chain](https://github.com/mozilla-neutrino/webpack-chain).
+
+``` js
+module.exports = {
+  chainWebpack: (config, isServer) => {
+    // config is an instance of ChainableConfig
+  }
+}
+```
+
+## Browser Compatibility
+
+### evergreen
+
+- Type: `boolean`
+- Default: `false`
+
+Set to `true` if you are only targeting evergreen browsers. This will disable ES5 transpilation and polyfills for IE, and result in faster builds and smaller files.
