Quark Masses, B-parameters, and CP violation parameters $\epsilon$ and   $\epsilon'/\epsilon$
  After a brief introduction to lattice QCD, I summarize the results for the light quark masses and the bag parameters $B_K$, $B_6^{1/2}$, and $B_8^{3/2}$. The implications of these results for the standard model estimates of CP violation parameters $\epsilon$ and $\epsilon'/\epsilon$ are also discussed.
