> Agent instructions:
> **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 [editor for rich text fields](https://docs.kentico.com/13/configuring-xperience/configuring-the-environment-for-content-editors/configuring-the-editor-for-rich-text-fields.md) in the administration interface provides spell-checking functionality.

The spelling checker uses a dictionary based on the currently chosen content culture. If no dictionary is available for the current content culture, the default dictionary is used. You can specify the default spelling checker dictionary in the **CMSDefaultSpellCheckerCulture** configuration key in the **appSettings** section of the administration project's **web.config** file.

## Adding additional dictionaries

The dictionaries are stored in the **CMS\App\_Data\Dictionaries** folder of your administration project. If you need additional dictionaries, you can download them from the following URLs:

Once downloaded, unpack them to the dictionary folder – **CMS\App\_Data\Dictionaries**. The file name of the dictionary must match the required culture code. For example: _fr-fr_

After adding a dictionary, you need to restart the administration application – open the **System** application in the administration interface and click **Restart application**.
