-prototype-rails provides Prototype, Scriptaculous, and RJS on Rails 3.1
-and later.
-
-Prototype and Scriptaculous are pulled in by the asset pipeline, so you don't
-need to copy the source files into your app. You may reference them in your
-s app/assets/javascripts/application.js:
-
-    //= require prototype
-    //= require prototype_ujs
-    //= require effects
-    //= require dragdrop
-    //= require controls
-
-prototype-rails supports RJS debugging. RJS responses are wrapped to catch
-exceptions, alert() them, and re-raise the exception. Debugging is disabled by
-default. To enable in development, set `config.action_view.debug_rjs = true`
-in config/environments/development.rb.

----

-## Support for Rails 4.1 and above
-
-Unfortunately, due to limited manpower and resources, the Rails core team has
-not been able to confirm if this gem currently works with Rails 4.1 and above.
-If you have found any problems while upgrading your application, please report
-them at the [issue tracker](https://github.com/rails/prototype-rails/issues),
-or better yet, submit patches by sending a [pull request](https://github.com/rails/prototype-rails/pulls).
-
-In any case, this gem will *NOT* be officially supported on Rails 5.0 and above.
+This fork provides thoroughly untested and unsupport Rails 7 compatability for `prototype-rails`.
