 = Spring Authorization Server
 
-Spring Authorization Server is a community-driven project led by the https://spring.io/projects/spring-security/[Spring Security] team and is focused on delivering https://tools.ietf.org/html/rfc6749#section-1.1[OAuth 2.0 Authorization Server] support to the Spring community.
+The Spring Authorization Server project, led by the https://spring.io/projects/spring-security/[Spring Security] team, is focused on delivering https://datatracker.ietf.org/doc/html/draft-ietf-oauth-v2-1-01#section-1.1[OAuth 2.1 Authorization Server] support to the Spring community.
 
-The project will start in Spring's experimental projects as an independent project so that it can evolve more rapidly.
-
-The ultimate goal of this project is to replace the Authorization Server support provided by https://spring.io/projects/spring-security-oauth/[Spring Security OAuth].
-
-With the much needed help from our community, this project will grow in the same way that the original Spring Security OAuth project did.
+This project replaces the Authorization Server support provided by https://spring.io/projects/spring-security-oauth/[Spring Security OAuth].
 
 == Feature Planning
 This project uses https://www.zenhub.com/[ZenHub] to prioritize the feature roadmap and help organize the project plan.
 The project board can be accessed https://app.zenhub.com/workspaces/authorization-server-5e8f3182b5e8f5841bfc4902/board?repos=248032165[here].
 It is recommended to install the ZenHub https://www.zenhub.com/extension[browser extension] as it integrates natively within GitHub's user interface.

 == Getting Started
-The first place to start is to read the https://tools.ietf.org/html/rfc6749[OAuth 2.0 Authorization Framework] to gain an in-depth understanding on how to build an Authorization Server.
-It is a critically important first step as the implementation must conform to the specification defined in the OAuth 2.0 Authorization Framework and the https://github.com/spring-projects-experimental/spring-authorization-server/wiki/OAuth-2.0-Specifications[related specifications].
