Where do I find the offline help files?

I find the process of getting help online rather time-consuming, and would like to have the help files on this computer, but I cannot find it/them. I am seeking En-UK for version 6.1.6

Go to Index of /libreoffice/old/6.1.6.2 , select the correct OperatingSystem /packages, in case of Win also the correct bit-width (which you also chose for LibO itself!) and dsownload the package you need.
