> 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).

On this tab, you can enhance the functionality of [Device profiles](https://docs.kentico.com/k82/developing-websites/developing-websites-for-mobile-devices/creating-device-profiles.md) by adding a [Premium 51Degrees.mobi](http://51degrees.mobi/Products/DeviceData.aspx) Data license key or uploading a Premium data .xml file. The Premium data version contains additional devices, e.g., game consoles, eBook readers, tablets and smart phones. It also contains additional properties in comparison with the Lite data version, which is included in Kentico by default.
