  This is a short presentation of our talks given at eRHIC Workshop at the BNL.
We give here a status report of our attempts to understand how gluon saturation
will manifest itself in deep inelastic scattering with nuclei. This summary
reflects our current understanding and shows directions of our research rather
then a final answer to the question. Nevertheless, we are able to share with
our reader our tentative answer to the question:``Why do we need to measure DIS
with nuclei and why these data will be complementary to the information
obtained from proton DIS".
