<APITable>
```

| Name | Type | Default | Description |
| --- | --- | --- | --- |
| `path` | `string` | `'docs'` | Path to the docs content directory on the file system, relative to site directory. |
| `editUrl` | <code>string \| [EditUrlFunction](#EditUrlFunction)</code> | `undefined` | Base URL to edit your site. The final URL is computed by `editUrl + relativeDocPath`. Using a function allows more nuanced control for each file. Omitting this variable entirely will disable edit links. |
| `editLocalizedFiles` | `boolean` | `false` | The edit URL will target the localized file, instead of the original unlocalized file. Ignored when `editUrl` is a function. |
| `editCurrentVersion` | `boolean` | `false` | The edit URL will always target the current version doc instead of older versions. Ignored when `editUrl` is a function. |
| `routeBasePath` | `string` | `'docs'` | URL route for the docs section of your site. **DO NOT** include a trailing slash. Use `/` for shipping docs without base path. |
| `tagsBasePath` | `string` | `'tags'` | URL route for the tags list page of your site. It is prepended to the `routeBasePath`. |
| `include` | `string[]` | `['**/*.{md,mdx}']` | Array of glob patterns matching Markdown files to be built, relative to the content path. |
| `exclude` | `string[]` | _See example configuration_ | Array of glob patterns matching Markdown files to be excluded. Serves as refinement based on the `include` option. |
| `sidebarPath` | <code>false \| string</code> | `undefined` | Path to sidebar configuration. Use `false` to disable sidebars, or `undefined` to create a fully autogenerated sidebar. |
| `sidebarCollapsible` | `boolean` | `true` | Whether sidebar categories are collapsible by default. See also [Collapsible categories](/docs/sidebar/items#collapsible-categories) |
| `sidebarCollapsed` | `boolean` | `true` | Whether sidebar categories are collapsed by default. See also [Expanded categories by default](/docs/sidebar/items#expanded-categories-by-default) |
| `sidebarItemsGenerator` | <code>[SidebarGenerator](#SidebarGenerator)</code> | _Omitted_ | Function used to replace the sidebar items of type `'autogenerated'` with real sidebar items (docs, categories, links...). See also [Customize the sidebar items generator](/docs/sidebar/autogenerated#customize-the-sidebar-items-generator) |
| `numberPrefixParser` | <code>boolean \| [PrefixParser](#PrefixParser)</code> | _Omitted_ | Custom parsing logic to extract number prefixes from file names. Use `false` to disable this behavior and leave the docs untouched, and `true` to use the default parser. See also [Using number prefixes](/docs/sidebar/autogenerated#using-number-prefixes) |
| `docsRootComponent` | `string` | `'@theme/DocsRoot'` | Parent component of all the docs plugin pages (including all versions). Stays mounted when navigation between docs pages and versions. |
| `docVersionRootComponent` | `string` | `'@theme/DocVersionLayout'` | Parent component of all docs pages of an individual version (doc pages with sidebars, tags pages). Stays mounted when navigation between pages of that specific version. |
| `docRootComponent` | `string` | `'@theme/DocPage'` | Parent component of all doc pages with sidebars (regular docs pages, category generated index pages). Stays mounted when navigation between such pages. |
| `docItemComponent` | `string` | `'@theme/DocItem'` | Main doc container, with TOC, pagination, etc. |
| `docTagsListComponent` | `string` | `'@theme/DocTagsListPage'` | Root component of the tags list page |
| `docTagDocListComponent` | `string` | `'@theme/DocTagDocListPage'` | Root component of the "docs containing tag X" page. |
| `docCategoryGeneratedIndexComponent` | `string` | `'@theme/DocCategoryGeneratedIndexPage'` | Root component of the generated category index page. |
| `remarkPlugins` | `any[]` | `[]` | Remark plugins passed to MDX. |
| `rehypePlugins` | `any[]` | `[]` | Rehype plugins passed to MDX. |
| `beforeDefaultRemarkPlugins` | `any[]` | `[]` | Custom Remark plugins passed to MDX before the default Docusaurus Remark plugins. |
| `beforeDefaultRehypePlugins` | `any[]` | `[]` | Custom Rehype plugins passed to MDX before the default Docusaurus Rehype plugins. |
| `showLastUpdateAuthor` | `boolean` | `false` | Whether to display the author who last updated the doc. |
| `showLastUpdateTime` | `boolean` | `false` | Whether to display the last date the doc was updated. This requires access to git history during the build, so will not work correctly with shallow clones (a common default for CI systems). |
| `breadcrumbs` | `boolean` | `true` | Enable or disable the breadcrumbs on doc pages. |
| `disableVersioning` | `boolean` | `false` | Explicitly disable versioning even when multiple versions exist. This will make the site only include the current version. Will error if `includeCurrentVersion: false` and `disableVersioning: true`. |
| `includeCurrentVersion` | `boolean` | `true` | Include the current version of your docs. |
| `lastVersion` | `string` | First version in `versions.json` | The version navigated to in priority and displayed by default for docs navbar items. |
| `onlyIncludeVersions` | `string[]` | All versions available | Only include a subset of all available versions. |
| `versions` | <code>[VersionsConfig](#VersionsConfig)</code> | `{}` | Independent customization of each version's properties. |
