I'm confused is it ckeditor 4 or 5 in latest version

Been using this repo for years, but on latest update to my app I can't get it working. There seems to be some discrepancies within the Readme!

It's CKE4 gem. If you want to use CKE5, consider switching to https://github.com/Mati365/ckeditor5-rails
