I have been looking for THE manual for using class 'article' in LaTex. The official CTAN package site points to some documentation which actually is 'an introduction to writing classes and packages for LATEX'; it does not cover how to use the article package.
I need to, for instance, check what is the command for inserting affiliations, or to place in-text references, among other typical tasks you will do while preparing a scientific paper. I would like to have the official way to do that at hand. Looking in Google for those commands returns disparate solutions relying on additional packages. And that is something I must avoid because of editorial regulations.
Can you please provide the link to a standard manual?
