This is an introduction to the equation of state (EOS) for stellar matter at subnuclear densities calculated with the Statistical Model for Supernova Matter (SMSM). Tables for EOS of the supernova matter are constructed for a wide range of the densities $\rho= (10^{-8}-0.32)\rho_0$, and of the temperatures $T=0.2-25$ MeV for different electron fractions $Y_e=0.02-0.56$. The cases of $\beta$-equilibrium are also considered. In this paper we explain the data structure and content of the SMSM EOS tables.
