Simple introduction to different modified gravities is given in relation with the universe history. Special attention is paid to F(R) gravity which is known to be ghost-free theory.
The realistic example of viable exponential F(R) gravity is given. It describes the evolution of the universe from inflation consistent with Planck data till dark epoch being consistent with observational data on the same level as LCDM theory.
Some ghost-free theories of F(R) and F(G) class with Lagrange multiplier are constructed. The reconstruction of realistic slow-roll inflation from F(R) gravity is proposed.
