 # Tink
 
-*A multi-language, cross-platform library that provides cryptographic APIs that
-are secure, easy to use correctly, and hard(er) to misuse. See also:
-https://developers.google.com/tink*.
-
-> **NOTE**: **Tink is moving!**
->
-> As part of our roadmap we are splitting Tink into
-> [multiple GitHub repositories][split_repo_roadmap_url] that will be hosted at
-> [github.com/tink-crypto](https://github.com/tink-crypto) and will be
-> independently versioned.
->
-> Roughly, we are going to create one repository per language, library extension
-> such as KMS (except Tink Python), and tools.
+> **NOTE**: **Tink moved to github.com/tink-crypto and this repository will be archived**
 >
-> A few important highlights:
+> As planned, we have split Tink into
+> [multiple GitHub repositories](https://developers.google.com/tink/roadmap#splitting_tink_into_multiple_github_repositories)
+> that are hosted at
+> [github.com/tink-crypto](https://github.com/tink-crypto). This repository is
+> going to be archived by the end of Q1 2024 (March 31st, 2024).
 >
-> -   The migration will be done gradually over the course of 2023 with a new
->     release from each of the new repositories. Releases will be announced in
->     our [mailing list][tink_mailing_list_url].
-> -   We will keep updating each implementation/tool in
->     [github.com/google/tink](https://github.com/google/tink) for a specified
->     amount of time; migrated implementations/tools will eventually stop being
->     updated on [github.com/google/tink](https://github.com/google/tink). The
->     support window depends on the specific implementation, as shown in the
->     table below.
-> -   New issues and pull requests should be created in the new repos.
+> All future releases will be made from repositories in
+> https://github.com/tink-crypto, which are independently versioned.

-> Below is the list of resulting repositories, migration timeline and expected
-> end of support.
