Recently there has been a successful non-linear covariant ghost-free generalization of Fierz-Pauli massive gravity theory, the dRGT theory. I will explore the recent developments within the framework of the dRGT theory. I will quickly discuss the cosmology in the decoupling limit of this theory. Furthermore, I will address the question whether or not the theory is stable under quantum corrections. The aforementioned theory requires the coexistence of two metrics and therefore it is a natural question of how the matter fields couple to these two metrics. I will present the latest developments in this direction as well.
