> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.
>
> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).
The following page lists all [widgets](https://docs.kentico.com/13/developing-websites/page-builder-development/developing-widgets.md) available for the [page builder](https://docs.kentico.com/13/developing-websites/page-builder-development.md) out-of-the-box. You may not see all of the default system widgets for some pages, depending on the [editable area limitations](https://docs.kentico.com/13/developing-websites/page-builder-development/creating-pages-with-editable-areas.md#limiting-components-allowed-in-an-editable-area) in your project.
> **Tip:** **Component identifiers**
>
> The identifiers of system components are available in the **SystemComponentIdentifiers** class (in the _Kentico.Content.Web.Mvc_ namespace). For example, use _SystemComponentIdentifiers.RICH\_TEXT\_WIDGET\_IDENTIFIER_ for the identifier of the _Rich text_ widget.
