 The main intent of `OAuth2AuthorizationServerConfiguration` is to provide a convenient method to apply the minimal default configuration for an OAuth2 authorization server. However, in most cases, customizing the configuration will be required.
 
-The following example shows how you can wire an authorization server with nothing more than an `HttpSecurity` builder while still re-using Spring Boot’s defaults for users and static resources:
-
-[source,java]

-@Bean
-SecurityFilterChain springSecurity(HttpSecurity http) {
-    http
-        .authorizeHttpRequests(requests -> requests
-            .anyRequest().authenticated()
-        )
-        .authorizationServer(auth -> auth
-            .oidc(Customizer.withDefaults())
-        )
-        .formLogin(Customizer.withDefaults());
-    return http.build();

+If you want to customize the default `HttpSecurity` configuration, you may override Spring Boot's auto-configuration with the following example:
+
+[[oauth2AuthorizationServer-minimal-sample-gettingstarted]]
+.SecurityConfig.java
+[source,java]
+----
+@Configuration
+@EnableWebSecurity
+public class SecurityConfig {
+
+	@Bean

+			.authorizeHttpRequests((authorize) ->
+				authorize
+					.anyRequest().authenticated()
+			)

+			.oauth2AuthorizationServer((authorizationServer) ->
+				authorizationServer

+			);

 TIP: Beyond the Getting Started experience, most users will want to customize the default configuration. The xref:servlet/oauth2/authorization-server/getting-started.adoc#oauth2AuthorizationServer-defining-required-components[next section] demonstrates providing all of the necessary beans yourself.
