I'm looking for an introductory (or rather, non-advanced) book on manifolds as locally ringed spaces, i.e., from the algebraic geometric viewpoint. Most introductory texts only introduce manifolds from the differentiable viewpoint; I wonder if a text introducing differential manifolds from an algebraic viewpoint exists.



Book on manifolds from a sheaf-theoretic/locally ringed space PoV
I'm not very familiar with this book (in particular, I don't know how introductory or not it is), but I think
