 We plan to support and maintain paperclip, as well as clean it up.
 
-Please feel free to contribute Issues and pull requests.
+**[Paperclip is deprecated]**.
+
+For new projects, we recommend Rails' own [ActiveStorage].
+
+For existing projects, please consult and contribute to the migration guide,
+available [in English], [en español], and as [a video] recorded at RailsConf
+2019. You may also prefer [an alternative migration tutorial used by
+Doorkeeper][].
+
+Alternatively, for existing projects, [Kreeti] is maintaining [kt-paperclip],
+an ongoing [fork of Paperclip].
+
+We will leave the Issues open as a discussion forum _only_. We do _not_
+guarantee a response from us in the Issues. All bug reports should go to
+kt-paperclip.
+
+We are no longer accepting pull requests _except_ pull requests against the
+migration guide. All other pull requests will be closed without merging.
