| Name | Type | Default | Description |
| --- | --- | --- | --- |
| `path` | `string` | `'docs'` | Path to the docs content directory on the file system, relative to site directory. |
| `editUrl` | <code>string \| <a href="#EditUrlFunction">EditUrlFunction</a></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#collapsible-categories) |
| `sidebarCollapsed` | `boolean` | `true` | Whether sidebar categories are collapsed by default. See also [Expanded categories by default](/docs/sidebar#expanded-categories-by-default) |
| `sidebarItemsGenerator` | <a href="#SidebarGenerator"><code>SidebarGenerator</code></a> | _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#customize-the-sidebar-items-generator) |
| `numberPrefixParser` | <code>boolean \|</code> <a href="#PrefixParser"><code>PrefixParser</code></a> | _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#using-number-prefixes) |
| `docLayoutComponent` | `string` | `'@theme/DocPage'` | Root layout component of each doc page. Provides the version data context, and is not unmounted when switching docs. |
| `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. |
| `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` | <a href="#VersionsConfig"><code>VersionsConfig</code></a> | `{}` | Independent customization of each version's properties. |
