The salience of satellite dwarf galaxies for understanding galaxy formation in a cosmological context has been made all the more evident in the past decade with the discovery of numerous faint Local Group galaxies. These faint systems are not only important to understand the faint end of galaxy formation but also their distribution around their host can test the hierarchical formation induced by the favored cosmological paradigm. I will review our successful effort to mine the two most ambitious surveys of the surroundings of the Milky Way and Andromeda galaxies, Pan-STARRS1 and PAndAS, for numerous new dwarf galaxies, before presenting the updated tally of MW/M31 satellites and what they are starting to tell us about galaxy formation in a LCDM universe.
