[help]how to obtain gravity eqution from gravity field Action S?

could you please tell me how to obtain gravity eqution from gravity field Action S as in detail as possible, especially the derivation of calculus of variations?
or you could point out some papers for me,
and thanks very very very very very very very very very much!
p.s. as in detail as possible! thanks!

For a careful treatment, see Chapter 4, Lagrangian and Hamiltonian formulations of general relativity, of the book A Relativist's Toolkit by Eric Poisson.
