Abstract
A short introduction to N = 1 supergravity in four dimensions in the superspace approach is given emphasising on all steps to obtain the final Lagrangian. In particular starting from geometrical principles and the introduction of superfields in curved superspace, the action coupling matter and gauge fields to supergravity is derived. This review is based on the book -A supergravity Primer: From geometrical principles to the Final Lagrangian- and on several lectures given at the doctoral school of Strasbourg.
