Where can we just download a non install required manual?

I am just looking for a PDF manual download that I can actually search without having to navigate inside the environment of the application? I don’t want ‘help’ keyed to the page I am on. I want to be able to search for a term and find it. The easy to use drop down cascading menus have all been replaced by ambiguous toolbars strewn everywhere.

Would it be possible to just have something that doesn’t have to be installed?

The place is / used to be / GIMP.LINUX.IT where there is / was / a Gimp 2.10 help as a PDF. Not available at the moment.

This is the most recent version that I have:
