Gravitational theories have received increased attention during the last years. The last observational cosmological advances have inspired a large number of theoretical models that attempt to explain them. Among other modifications of Einstein's General Relativity, there are the f(R) theories, whose action depends on a general form of the scalar curvature. I will review basic aspects of these models paying particular attention to the following subjects within this framework: chameleon mechanism, dark matter, gravitational collapse, black holes, focusing theorem,...
