A few decades ago, Larry Evans published an explanation of the first moves of the Ruy Lopez (Spanish), with a detailed explanation of each move. It's almost certainly available online for anyone who wants to learn how to learn the openings.
It's absolutely fine to learn the openings. But do so organically. Learn why each move is important, what the threats are, and what the ideas behind the opening moves are.
Do not just learn which moves are best, learn why each move is played and whether or not there are tactical considerations. You can learn the openings and learn tactics at the same time!

What is opening theory exactly?
Much of chess language does not have exact meanings. Nobody is in charge of that sort of thing. Two beginner opening books are Openings for Amateurs by Pete Tamburro (2014)
and Discovering Chess Openings by GM Johm Emms (2006).
I believe that it is possible to see a fair portion of the beginning of Tamburro's book by
going to the Mongoose Press site.
i think the larry evans book is called - how to open a chess game- but the chapter is by svetozar gligoric
