The nonperturbative quantization procedure of LQG is successfully extended to a rather general class of 4-dimensional metric theories of gravity, which have received increased attention recently due to motivations coming from cosmology and astrophysics. I will introduce how to reformulate the 4-dimensional scalar-tensor theories of gravity, including $f(R)$ theories, into connection-dynamical formalism with real $SU(2)$ connections as configuration variables.
