 Starlight is ready for you to add new content, or bring your existing files!
 
-#### File formats
+Add new pages to your site by creating Markdown files in the `src/content/docs/` directory.
 
-Starlight supports authoring content in Markdown and MDX with no configuration required.
-You can add support for Markdoc by installing the experimental [Astro Markdoc integration](https://docs.astro.build/en/guides/integrations-guide/markdoc/).
-
-#### Add pages
-
-Add new pages to your site by creating `.md` or `.mdx` files in `src/content/docs/`.
-Use sub-folders to organize your files and to create multiple path segments.
-
-For example, the following file structure will generate pages at `example.com/hello-world` and `example.com/guides/faq`:
-
-import FileTree from '~/components/file-tree.astro';
-
-<FileTree>
-
-- src/
-  - content/
-    - docs/
-      - guides/
-        - faq.md
-      - hello-world.md
-
-</FileTree>
-
-#### Type-safe frontmatter
-
-All Starlight pages share a customizable [common set of frontmatter properties](/reference/frontmatter/) to control how the page appears:
-
-```md
----
-title: Hello, World!
-description: This is a page in my Starlight-powered site
----
-```
-
-If you forget anything important, Starlight will let you know.

+sidebar:
+  order: 1
+---
+
+Starlight generates your site’s HTML pages based on your content, with flexible options provided via Markdown frontmatter.
+In addition, Starlight projects have full access to [Astro’s powerful page generation tools](https://docs.astro.build/en/basics/astro-pages/).
+This guide shows how page generation works in Starlight.
+
+## Content pages
+
+### File formats
+
+Starlight supports authoring content in Markdown and MDX with no configuration required.
+You can add support for Markdoc by installing the experimental [Astro Markdoc integration](https://docs.astro.build/en/guides/integrations-guide/markdoc/).
+
+### Add pages
+
+Add new pages to your site by creating `.md` or `.mdx` files in `src/content/docs/`.
+Use sub-folders to organize your files and to create multiple path segments.
+
+For example, the following file structure will generate pages at `example.com/hello-world` and `example.com/reference/faq`:
+
+import FileTree from '~/components/file-tree.astro';
+
+<FileTree>
+
+- src/
+  - content/
+    - docs/
+      - hello-world.md
+      - reference/
+        - faq.md
+
+</FileTree>
+
+### Type-safe frontmatter
+
+All Starlight pages share a customizable [common set of frontmatter properties](/reference/frontmatter/) to control how the page appears:
+
+```md
+---
+title: Hello, World!
+description: This is a page in my Starlight-powered site
+---
+```
+
+If you forget anything important, Starlight will let you know.
+
+## Custom pages
+
+For advanced use cases, you can add custom pages by creating a `src/pages/` directory.
+The `src/pages/` directory uses [Astro's file-based routing](https://docs.astro.build/en/basics/astro-pages/#file-based-routing) and includes support for `.astro` files amongst other page formats.
+This is helpful if you need to build pages with a completely custom layout or generate a page from an alternative data source.
+
+For example, this project mixes Markdown content in `src/content/docs/` with Astro and HTML routes in `src/pages/`:
+
+<FileTree>
+
+- src/
+  - content/
+    - docs/
+      - hello-world.md
+  - pages/
+    - custom.astro
+    - archived.html
+
+</FileTree>
+
+Read more in the [“Pages” guide in the Astro docs](https://docs.astro.build/en/basics/astro-pages/).
+
+### Using Starlight’s design in custom pages
+
+To use the Starlight layout in custom pages, wrap your page content with the `<StarlightPage />` component.
+This can be helpful if you are generating content dynamically but still want to use Starlight’s design.
+
+```astro
+---
+// src/pages/custom-page/example.astro
+import StarlightPage from '@astrojs/starlight/components/StarlightPage.astro';
+import CustomComponent from './CustomComponent.astro';
+---
+
+<StarlightPage frontmatter={{ title: 'My custom page' }}>
+	<p>This is a custom page with a custom component:</p>
+	<CustomComponent />
+</StarlightPage>
+```
+
+#### Props
+
+The `<StarlightPage />` component accepts the following props.
+
+##### `frontmatter` (required)
+
+**type:** `StarlightPageFrontmatter`
+
+Set the [frontmatter properties](/reference/frontmatter/) for this page, similar to frontmatter in Markdown pages.
+The [`title`](/reference/frontmatter/#title-required) property is required and all other properties are optional.
+
+The following properties differ from Markdown frontmatter:
+
+- The [`slug`](/reference/frontmatter/#slug) property is not supported and is automatically set based on the custom page’s URL.
+- The [`editUrl`](/reference/frontmatter/#editurl) option requires a URL to display an edit link.
+- The [`sidebar`](/reference/frontmatter/#sidebar) property is not supported. In Markdown frontmatter, this option allows customization of [autogenerated link groups](/reference/configuration/#sidebar), which is not applicable to pages using the `<StarlightPage />` component.
+
+{/* ##### `sidebar` */}
+
+{/* **type:** `SidebarEntry[] | undefined` */}
+{/* **default:** the sidebar generated based on the [global `sidebar` config](/reference/configuration/#sidebar) */}
+
+{/* Provide a custom site navigation sidebar for this page. */}
+{/* If not set, the page will use the default global sidebar. */}
+
+##### `hasSidebar`
+
+**type:** `boolean`  
+**default:** `false` if [`frontmatter.template`](/reference/frontmatter/#template) is `'splash'`, otherwise `true`
+
+Control whether or not the sidebar should be displayed on this page.
+
+##### `headings`
+
+**type:** `{ depth: number; slug: string; text: string }[]`  
+**default:** `[]`
+
+Provide an array of all the headings on this page.
+Starlight will generate the page table of contents from these headings if provided.
+
+##### `dir`
+
+**type:** `'ltr' | 'rtl'`  
+**default:** the writing direction for the current locale
+
+Set the writing direction for this page’s content.
+
+##### `lang`
+
+**type:** `string`  
+**default:** the language of the current locale
+
+Set the BCP-47 language tag for this page’s content, e.g. `en`, `zh-CN`, or `pt-BR`.
+
+##### `isFallback`
+
+**type:** `boolean`  
+**default:** `false`
+
+Indicate if this page is using [fallback content](/guides/i18n/#fallback-content) because there is no translation for the current language.
