+[OpenID Connect 1.0](https://openid.net/connect/) is a authorization identity framework supported by Authelia. You can
+configure your applications to use Authelia as an [OpenID Connect 1.0 Provider](https://openid.net/connect/). We do not
+currently operate as an [OpenID Connect 1.0 Relying Party](https://openid.net/connect/). This like all single-sign on
+technologies requires support by the protected application.
+
+See the [OpenID Connect 1.0 Configuration Guide](../../configuration/identity-providers/open-id-connect.md) and the
+[OpenID Connect 1.0 Integration Guide](../../integration/openid-connect/introduction.md) for more information.

+This mechanism is supported by proxies which inject certain response headers from Authelia into the protected
+application. This is a very basic means that allows the target application to identify the user who is logged in
+to Authelia. This like all single-sign on technologies requires support by the protected application.
+
+You can read more about this in the [Trusted Header SSO Integration Guide](../../integration/trusted-header-sso/introduction.md).
