> **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).

To enable Microsoft account sign-in for your website, you need to register a Microsoft application:

1. Sign in to the [Microsoft Application Registration Portal (https://apps.dev.microsoft.com/)](https://apps.dev.microsoft.com/) using your Microsoft account.
2. Click **Add an app** in the **Live SDK applications** section.
3. Enter an appropriate **Name** for your authentication application.
4. Click **Create application**.
5. In the **Platforms** section, configure a **Web** platform for your Kentico website (either use the default Web platform or create a new one):
   1. Type your website's domain name into the **Target Domain** field.
   2. Add the URL of your website's _CMSPages/LiveIDLogin.aspx_ system page to the **Redirect URIs**.
      - Use the fully qualified domain name (including the protocol and virtual directory, if applicable).
      - For example: _http://kenticositedomain.com/CMSPages/LiveIDLogin.aspx_
   3. Click **Add Url** to create another Redirect URI and enter the full URL of your website's default page (Home page).
      - The site's default URL depends on the **Content -> Default alias path** and **URLs and SEO -> Default page** settings.
      - Include the default URL extension used by your website.
6. Click **Save**.
7. Copy the **Application Id** and **Application Secret** values. You need to enter the values into the corresponding [settings in Kentico](https://docs.kentico.com/k81/managing-users/user-registration-and-authentication/windows-live-id-authentication/configuring-windows-live-id-authentication.md).
