TITLE: supermanifolds - elementary introduction?
QUESTION [16 upvotes]: I am looking for an elementary but mathematically precise introductory text on supermanifolds in a modern differential geometric setting. 
Elementary in the sense that there is plenty of motivation for the concepts and methods, and that these are explained in some detail with simple examples featuring only few bosonic and one fermionic coordinates, for example $R^{1|1}$ or $OSp(1|1)$.

REPLY [3 votes]: I would like to add Riemannian supergeometry by Oliver Goertsches. Abstract:

Motivated by Zirnbauer in J Math Phys 37(10):4986–5018 (1996), we develop a theory of Riemannian supermanifolds up to a definition of Riemannian symmetric superspaces. Various fundamental concepts needed for the study of these spaces both from the Riemannian and the Lie theoretical viewpoint are introduced, e.g., geodesics, isometry groups and invariant metrics on Lie supergroups and homogeneous superspaces.
