This leads to a table with an overview of supergravity and supersymmetry theories in dimensions 4 to 11. The basic steps in constructing supergravity theories are considered: determination of the underlying algebra, the multiplets, the actions, and solutions. Finally, an overview is given of the geometries that result from the scalars of supergravity theories.30 pages; contribution to the Proceedings of the XI Fall Workshop on Geometry and Physics, Oviedo (Spain), September 23-25 (2002), to be published in the series "Publications of the Royal Spanish Mathematical Society"; v.2: typos correctedHigh Energy Physics - Theorytext
