I think there are several good references. For instance:


R. O. Wells: *Differential Analysis on complex manifolds* (Springer GTM **65**), Chapter III.

J. D. Moore: *Lectures in Seiberg-Witten invariants* (Springer LNM **1629**), Chapter 1. 

D. Huybrechts: *Complex Geometry - An introduction* (Springer Universitext), Chapter 2.
