Thread:Extension talk:Cite/Extension requires Modules, which Installation instructions say nothing about!

OK, so I installed this extension and followed the manual install instructions exactly as this page discusses.

However, all the ref citations attempted resulted in script failures.

It looks to me like there was a complete failure to load in or add the Module:Citation/CS1, Date_validator, Whitelist (and maybe one more, I forget).

I wound up adding those by hand by copying code from https://en.wikipedia.org/wiki/Module:Citation/CS1 (etc) which seems just... nasty.

Did I miss something? Did I install the extension incorrectly? Or am I actually supposed to go through and create those Module: files in my wiki? If the latter, it seems to me that the instructions for installing this extension should mention the need to add in the modules, plus pointers so that other folks don't wind up googling their day away to figure this out.

Thanks.
