+This guide provides instructions on setting up this SAML 2.0 Login sample application.
 
-The sample application uses Spring Boot 2.2.0.M5 and the `spring-security-saml2-service-provider`
+The sample application uses Spring Boot and the `spring-security-saml2-service-provider`
 module which is new in Spring Security 5.2.
 
 == Goals
 
-`saml2Login()` provides a very simple, basic, implementation of a Service Provider
-that can receive a SAML 2 Response XML object via the HTTP-POST and HTTP-REDIRECT bindings
-against a known SAML reference implementation by SimpleSAMLPhp.

-The following features are implemented in the MVP
-
-1. Receive and validate a SAML 2.0 Response object containing an assertion
-and create a valid authentication in Spring Security
-2. Send a SAML 2 AuthNRequest object to an Identity Provider
-3. Provide a framework for components used in SAML 2.0 authentication that can
-be swapped by configuration
-4. Sample working against the SimpleSAMLPhP reference implementation
