The details of the early star formation history of isolated dwarf galaxies can shed light on the role of the cosmic re-ionization and supernova feedback in galaxy formation and evolution. In this paper, we present the project { Local Cosmology from Isolated Dwarfs (LCID), aimed at deriving detailed star formation histories for a sample of Local Group isolated dwarf galaxies. To accomplish this goal we have collected, using the ACS on board the HST, color-magnitude diagrams reaching their oldest main sequence turnoff (V≃29 mag) with good photometric accuracy. Some results are briefly discussed.
