> 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).

Notifications allow the system to automatically send out messages informing about certain events. By default, the system can send notifications for the following events:

- Page created
- Page updated
- Page deleted

Kentico comes with a built-in email notification gateway. Your developers can also implement custom gateways, for example SMS or instant messaging providers. Note that for one event, users can obtain notification messages from multiple providers.

Notifications have only one setting in **Settings -> System**.

- **Send email notifications from** – sets the email address used as the sender (the **From** field) of notification emails.
