Note The `description` field is a Nimbus built-in, not a custom property, but it is required for all pages with a `pcx_content_type`. For writing guidance, refer to [Writing a description](https://developers.cloudflare.com/style-guide/build-the-page/frontmatter/#writing-a-description). ## Properties ### banner **Type:** `object` optional **Description:** Displays a [Banner](https://developers.cloudflare.com/style-guide/build-the-page/frontmatter/banner/) on the current docs page. ### canonical **Type:** `string` optional **Description:** A canonical URL or path to set as the `` in the page ``, overriding the default derived from the page URL. ### difficulty **Type:** `string` optional **Description:** Difficulty is displayed as a column in the [ListTutorials component](https://developers.cloudflare.com/style-guide/build-the-page/components/list-tutorials/). ### external\_link **Type:** `string` optional **Description:** Path to another page in our docs or elsewhere. Used to add a crosslink entry to the lefthand navigation sidebar. ### feedback **Type:** `boolean` **Description:** Whether to show the FeedbackPrompt on the page, defaults to true ### hideChildren **Type:** `boolean` optional **Description:** Renders this group as a single link on the sidebar, to the index page. Refer to [Sidebar](https://developers.cloudflare.com/style-guide/build-the-page/frontmatter/sidebar/). ### noindex **Type:** `boolean` optional **Description:** If true, this property adds a `noindex` declaration to the page, which will tell internal / external search crawlers to ignore this page. Helpful for pages that are historically accurate, but no longer recommended, such as [Workers Sites](https://developers.cloudflare.com/workers/configuration/sites/). ### pcx\_content\_type **Type:** `string` optional **Description:** The purpose of the page, and defined through specific pages in [Content strategy](https://developers.cloudflare.com/style-guide/documentation-content-strategy/content-types/). ### products **Type:** `array` **Description:** The names of related directory entries (according to their file name in `src/content/directory`). Usually, these correspond to file paths, but not always, such as with `cloudflare-tunnel` ### release\_notes\_file\_name **Type:** `array` optional **Description:** Required for the [ProductReleaseNotes](https://developers.cloudflare.com/style-guide/build-the-page/components/usage/#productreleasenotes) component. ### reviewed **Type:** `undefined` optional **Description:** A `YYYY-MM-DD` value that signals when the page was last explicitly reviewed from beginning to end. ### sidebar **Type:** `object` **Description:** Used to configure various sidebar options. Refer to [Sidebar](https://developers.cloudflare.com/style-guide/build-the-page/frontmatter/sidebar/). ### styleGuide **Type:** `object` optional **Description:** Used by overrides for style guide component documentation, which helps us display the [usage counts](https://developers.cloudflare.com/style-guide/build-the-page/components/usage/) for components directly on the component page itself. ### summary **Type:** `string` optional **Description:** Renders a summary description directly below the page title. ### tags **Type:** `array` optional **Description:** A group of related keywords relating to the purpose of the page.
